morta

The slag can improve the workability of the morta , and also enhance strength and softness coefficient , increase thermal conductivity .

炉渣的掺入改善了砂浆的和易性，提高了砂浆的强度和软化系数，增大了砂浆的导热系数。

Low strength pile is the plain concrete pile , including cement mixing pile ; cement morta pile ; high-pressure rotary jet grouting pile ; CFG pile etc. , which strength is lower then reinforced concrete pile .

低强度桩包括水泥搅拌桩、水泥砂浆桩、高压旋喷桩、CFG桩等强度比钢筋混凝土桩低的多的素混凝土类桩。

In this paper , the deformation , microcrack initiation and propagation of pumice-aggregate foamed concrete , morta , pumice-aggregate and interfacial ring in the concrete are studied under monoaxial compressive stress .

本文对单轴压应力下浮石泡沫混凝土及混凝土中浮石粗集料、砂浆、界面过渡层的变形和微裂纹的产生和扩展进行了试验研究。
