HELPING THE OTHERS REALIZE THE ADVANTAGES OF CONCRETE ADDITIVES

Anionic surfactant has more robust adsorption on surface area of cement than that on area of montmorillonite, granite and limestone. But cationic and nonionic surfactants have much stronger adsorption on area of montmorillonite and granite than that on floor of cement. When montmorillonite, granite and limestone are extra into cement mortar, the ai

This do the job takes advantage of X-ray computed micro tomography (XCT) to analyze the job on the significant diploma of saturation (DOS) and air void system on the crack propagation of portland cement mortar subjected to freeze-thaw cycles. 3-dimensional imaging before and immediately after freezing allow for quantitative measurements on the loca
