Do u know wat is concrete made of????Originally posted by shade343:If the construction industry slowly weans itself from sand, the demand for sand will decline.
In future, look forward to new buildings that uses steel reinforcement rather than concrete reinforcement.
Alternatively, if somebody finds a way to make reinforced concrete without the use of concreting sand, all the better.
Cement,sand and agg!!!!depending on ratios only!!!
W/o sand there is no concrete!!!
I think u r a PSLE holder like OM!!! -
100 %!!Originally posted by ShutterBug:Logically, I EXPECT costs of private developments will escalate as a result of this ban.
No one should expect cost of sand from further away country to be acquired at same price.
I just feel that this sandy issue can pave way to some degree of economic stumbles in the VERY near future. It has already started a cost-ripple... and its spreading...
Sorry,using yr thread 2 play with this little boy,Shade 343!! -
Sand is a non-substitutable component of concrete. But I don't recall sand being used in cement powder manufacture? -
Yup, definitely cost will go up, and a building cant be 100% steel. How much would depend on whether genting has already tendered out the project to the main contractor or not. If they had called for tender last year, their cost might be lower. If they were to call for tender now, their cost would be higher as contractors would factor in the increase of price in raw materials.Originally posted by maurizio13:Makes sense, but still can't totally do away with the use of sand.
I think cost will go up.
I think the cost of building the IR will go up, unanticipated by Genting.
Maybe they can source from Malaysia, afterall they are Malaysian listed company. -
I m not making cement powder,dont know,leh!!!Originally posted by ShutterBug:Sand is a non-substitutable component of concrete. But I don't recall sand being used in cement powder manufacture?

Again you show how dumb you are. Its without concrete there wouldnt be a need for sand. Not the other way round. Sand and coarse aggregates are needed to add strength to the concrete.Originally posted by foomwee88:Do u know wat is concrete made of????

Concrete by itself is not strong. Surely you should know all these from your lab tests if you are a BLD SCI Degree holder. I wonder how you manage to get into NUS with such shallow command of english.

F U C K you!!! What you know about construction?Originally posted by shade343:Are you dumb or something? You sound like you dont study construction and yet you speculate on the amount of sand a building needs. Have you ever heard of steel reinforcement?
I've been in construction for twenty years!!! God damn it!!!
1 cubic metre of G30 concrete, what the amount sand required? Can you tell us? -
OMG. DOnt you know that timber has to be tanalised and treated for water resistivity?Originally posted by foomwee88:Timber partitioned walls would be badly affected by the ingress of h2o,how ah, like the 2 LPs internally inundated with h20 and fff soaked with water all were ruined !!!
Experts,how ah!!!
And who ask you so dumb to use timber in an area of the building that is exposed to a high amount of moisture?
You sure you are from NUS or not?
Stop disgracing NUS you uneducated laymen. -
Yes, circumstances whereby contracts were signed earlier, will face costing problems now.Originally posted by shade343:Yup, definitely cost will go up, and a building cant be 100% steel.

And it would not be isolated cases... -

Reinforced gr 30 conc of cos consist of 1 part cement and 3 parts sand. -

Portland cement is the most common type of cement in general usage, as it is a basic ingredient of concrete, mortar and most non-specialty grout. It is a finely-ground powder produced by grinding Portland cement clinker (more than 90%), a maximum of about 5% gypsum which controls the set time, and up to 5% minor constituents (as allowed by various standards). As defined by the European Standard EN197.1, Portland cement clinker is a hydraulic material which shall consist of at least two-thirds by mass of calcium silicates (3CaO.SiO2 and 2CaO.SiO2), the remainder consisting of aluminium- and iron-containing clinker phases and other compounds. The ratio of CaO to SiO2 shall not be less than 2.0. The magnesium content (MgO) shall not exceed 5.0% by mass. (The last two requirements were already set out in the German Standard, issued in 1909). Portland cement clinker is made by heating, in a kiln, an homogenous mixture of raw materials to a sintering temperature, which is about 1450 °C for modern cements. The aluminium oxide and iron oxide are present as a flux and contribute little to the strength. For special cements, such as Low Heat (LH) and Sulfate Resistance (SR), it is necessary to limit the amount of tricalcium aluminate (3CaO.Al2O3) formed. The major raw material for the clinker-making is limestone (CaCO3). Normally, an impure limestone which contains SiO2 is used - the CaCO3 content can be as low as 80%. Secondary raw materials depend on the purity of the limestone. Some of the secondary raw materials used are: clay, shale, sand, iron ore, bauxite, fly ash and slag. When a cement kiln is fired by coal, the ash of the coal becomes a secondary raw material.
Do you know concrete means?
Concrete is a construction material that consists, in its most common form, of Portland cement, aggregate (generally gravel and sand) and water.
F U C K You!!!! -
steel might make building the house easy, but the weight it adds to the structure means another thing. I believe the reclaim land use a lot of sand ... I tot there was plans to reclaim more land.. there are multiple areas that are affected, not just buildings.
Never had thought that sand can cause so much issues. the sand pile in bedok reservoir has gone down 2 levels... Its quite drastic. -
You talking to meOriginally posted by shade343:Really? Which construction firm are you from?
Reinforced gr 30 conc of cos consist of 1 part cement and 3 parts sand. the design mix for concrete???
You go and die lah.....
G30 concrete
Mininum crushing strength 22.5N/mm2 for 7 days
Min. cruching strength 30N/mm2 for 28 days
Mininum cement required = 405 kg per cu m.
Maximum cement required = 550 kg per cu.m
Maximum cement water / cement ratio = 0.45
You understand??? -
Yes, indeed..Originally posted by mistyblue:Never had thought that sand can cause so much issues. .
oftentimes, the commonest of things in our lives can be quite a niggler... -
Well, I never thought that a sand issue can turn into a flaming war.Originally posted by ShutterBug:Yes, indeed..

Worldwide, there is a shortage of metal.. scrap value of metal is so high have no one noticed that coffee shop uncle would recycle your drink cans?
To think of using metal as replacement ... I think HDB is already costly enough ... I do not want to pay anymore than necessary for housing. But for all you know. all these charade might just be wayang to get housing price shooting up the roof. -
Well, if contributors to this topic will stick to the subject WITHOUT getting too personal with remarks, then there's no danger of escalations into flamings.Originally posted by Hogzilla:Well, I never thought that a sand issue can turn into a flaming war.
After all, we're in here to air our views, professionals or not....
And it would be good to stop trying to outshine one another.. it'll never end. -
OOhh yah... this is also one notion that's been niggling at the back of my neck eversince the Sand Ban was announced...Originally posted by mistyblue:Worldwide, there is a shortage of metal.. scrap value of metal is so high have no one noticed that coffee shop uncle would recycle your drink cans?

If HDB housing costs goes up, it WILL affect consumer sentiments, which means worse retail figures as well as in the service industry...

Which uni u come from!!!!!
We hve tanalised bakau pilings for foundation work only!!!where in the world we need treatment to partitioned walls!!!!
Pls dont make a fool of yrself like OM!!!!
Do u know wat is 1:2:4 and 1:3:6 for concrete grade i.e cement:sand and aggr and water ratios!!!!
u r a real Bull shitter!!!!! know nothing but want to act like one know wat!!!! -
Dude... if you want to carry this on, please do so via PM... I mean all this talk is not really helping the actual discussion here... not to mention a real eyesore.

Do u know in the 1990s b4 1997 who was the one spent in rests, niteclubs and shares market,the contractors!!!!the profit margin is more than 20%,and now is merely 5% per 2-3 yrs contract that why all die 2!!!
Asia market like in Spore depending 2 much on property development market including construction ind,which is very dangerous when the raw material prices go up which will eat into the profit margin and the only way out is to cur corner but they can only dream of this in Spore cauz we hve 2 many qualified engineers who will not risk their rice bowl for such a thing unlike those self-proclaimed ones here!!!
Property developers will hve their first shot if the constuction costs going up and contractors who committed to projects but hve no prices escalation
clause included in the blg k will go bankrupt which in turn the whole sector of our economic will face inflation same as in the 1970s!!!interest rates will shot up like 20% per yr!!!!
No eye 2 c by then!!!! -
OMG. NOW YOU ARE AN OFFICIAL FAKER AND A LIAR. From your post, you insinuate that gypsum is a form of timber. I never said that. But you said it.Originally posted by foomwee88:R u sure gypsum board partitioned walling can be tanalised and treated for water resisitance!!!

u r a real Bull shitter!!!!! know nothing but want to act like one know wat!!!! I thought you were talking about timber partitioning which is a ENTIRELY DIFFERENT subject matter.
But I pasted the following below for the convenience of all to show how stupid and dumb you are for saying that gypsum boards are made of timber.Originally posted by shade343:Other ways to cut down on sand for interior use would be using gypsum boards for partitioning.
Oh, and now you want to test my knowledge on concrete mixture eh? You need my help in answering your construction homework ah? Poor thing. all those ratios you stated refers to the constituent amount in concrete mixture. 1:2:4 refers to 1 part cement, 2 parts sand and 4 parts coarse aggregate.
Originally posted by foomwee88:Timber partitioned walls would be badly affected by the ingress of h2o,how ah, like the 2 LPs internally inundated with h20 and fff soaked with water all were ruined !!!
Experts,how ah!!!
How about my turn to test you?
Tell me what does BS 4449 state and tell me when is such a standard applied. Can you answer? If you cant, maybe you should jolly well shut the fuck up and get loss. Pathetic pretender. Only know how to quote random statements from the internet. -
Hey I agree, but I really cant stand people who post crap here without bothering to research on the subject matter and making wild statements and accusations at the government.Originally posted by SingaporeTyrannosaur:Dude... if you want to carry this on, please do so via PM... I mean all this talk is not really helping the actual discussion here... not to mention a real eyesore.
And worst, one of them claims to be a graduate from NUS in building science and he can tell me that gypsum board is made from timber.
