水泥轻舟轻质高强砂浆的设计

Design of Light-weight and High-strength Mortar for Cement Canoe

为了在最大程度上降低轻舟重量的同时保证水泥轻舟有足够的强度,通过控制各种材料的掺入量来确定水泥砂浆的最佳配比组成,其主要技术指标是砂浆成型后的抗折强度和密度。实验证明,膨胀珍珠岩可以在保证一定强度的情况下降低砂浆的密度,达到轻质效果;矿渣有利于废物综合利用,并且能够提高砂浆的抗折强度;玻璃纤维能够提高砂浆强度。研究设计出的水泥砂浆达到了轻质高强的要求。

In order to reduce the weight and at the same time guarantee the enough strength of the concrete canoe to the usmost, the optimum proportion of cement mortar can be determined through the control of various adding materials, whose main technical indexes are the flexural strength and denisity after mortar moudling. The experiment shows that in a certain strength , the expanded perlite can reduce the density of the mortar to achieve light -weight effect; the slag can be of use for the waste comprehensive utilization, and the flexural strength of mortar can be improved. The glass fiber can increase the strength of concrete. The designed mortar can meet the requirements of lightweight and high strength.
