Adopting such three fields as modified ligneous calcium, the compound use of leading gas agent and various maintainable conditions, the problem of improving the cubic stability of low cement-water ratio concrete with a large additive amount of grinding fine ore is discussed.

Application of high-proportion fine slag concrete to Tianjin Section of Mid-route of South-to-North Water Transfer Project;

Research on properties of concrete with pre-hydrated fly ash and grounded furnace slag;

By test of performances effect recycled mill admitxture and grounded furnace slag on concrete,on the basis of diverse characteristics influence of each on concrete,adopting admitxture compound technique makes admitxture properties;advantage complement.

The concrete with massive micro-cinder powders has contributed a lot to anti-corrosion from seawater, so which is spreading on hydraulic engineering programs in coastlands of Guangdong province.
