研究了泡沫-EPS保温砂浆的导热系数与干密度的关系。
The relationship between coefficient of thermal transmission and dry density of foamed EPS thermal insulation mortar is also researched.
考察了SAE对水泥砂浆的密度、吸水性、凝结时间以及水泥水化速度的影响。
The effects of SAE on the density, absorbency, setting time and cement hydration of cement mortars were studied.
结果表明，加入SAE使水泥砂浆的表观密度降低，吸水率下降，并且明显延缓了水泥的凝结时间及水化速度。
The results show that the SAE copolymer emulsion not only reduce the apparent density and absorb water rate of cement mortar, but significantly retard the setting and the hydration of portland cement.
D623提高保水新鲜砂浆和夹带了大量的微空隙，这会导致堆积密度降低，孔径分布改变。
D623 improves water retention of fresh mortar and entrains a large amount of micro air void which causes bulk density to reduce, pore size distribution to change.
