DURABILITY AT OTHER ONE:UTILIZATION OF DESERT SAND AND SEA SAND FOR SUSTAINABLE DEVELOPMENT OF CONCRETE
For Sustainable Development,on the one hand,that is to search out some ways tominimize an amount consumed of water,cement and quality aggregate for a majority of. Forexample,in northwest area of China,to the local natural sand of desert using a kind ofcementitious material named HPCM(high performance consolidating material) containinghigh volume industrial waste instead of substitution of dug out sand and using a smallquantity of water (w/c is less than 100 kg/m3) is being practiced for road and highway indesert area. On the other hand,in southeast,there is the very wide shoreline,and very rich insea sand,sea water. For sea side infrastructure with unreinforced concrete such as sea wall,road by sea side,etc.,the sea sand can be solidified by that cementitious material HPCM also,and the sea water can be used for mixing. Considering durability of these infrastructures,HPCM material should be better than the general aggregate and mix water apparently.
