Are You Mining Minerals for Cement, or for Concrete? Many people use the words cement and concrete interchangeably. However, these are actually two, somewhat different things. Cement is the grey powdery stuff that when mixed with sand, rock, gravel and water forms concrete. The concrete is the...
In many domestic airport pavement design, there are two main forms of road surface cement concrete pavement and asphalt concrete road surface. But because of our vast natural conditions and levels of development in different regions vary greatly, airport construction with substantial gaps, this requ ...

for cement application [15]. Recently,focal pointof MD simulations on cement has been put on hydration products of alite, belite and C3A. The hydration products are constituents of hardened cement and are closely related to the mechanical performance of cement as well as concrete. Among the ...
The results obtained from a compressive strength test, leaching test, and thermal cycling test of cement waste forms conclude that the concrete waste, water, and cement have been suggested as an optimized mixing ratio of 75:15:10. In addition, the compressive strength of the cement waste form...
Normally a concrete composition requires a high slump in order to fill the void between the forms or to pump the concrete composition. It is believed that the sodium silicate of the present invention acts as a lubricant, making the low slump cement composition pumpable through conventional concret...
