不同原料土的气泡轻质土制备与性能对比

选用多种原料土制备气泡轻质土,详细的研究其物理力学性能。对比了不同比例原料土掺入时湿重度、流动度、无侧限抗压强度和造价的差异。结果表明:以机制砂制备的气泡轻质土的强度总体上大于河砂、淡化海砂和黏土质砂;在保证水固比不变的前提下,增加黏土质砂的掺入比例流动度增加,而抗压强度会减少小;在满足一定抗压强度下,选用黏土质砂时的造价最低。

Preparation and Performance Comparison of Bubble Light Soil with Different Raw Materials

A variety of raw material soils are used to prepare bubble light soil,and their physical and mechanical properties are studied in detail.The differences of wet weight,fluidity,unconfined compressive strength,and cost when different proportions of raw material soils are compared.The results show that the strength of the bubble light soil made from machined sand is generally greater than that of river sand,desalinated sea sand,and clay sand;and under the premise of ensuring that the water-solid ratio is constant,increasing the proportion of clay sand increases the fluidity,but the compressive strength will be reduced;under certain compressive strength,the cost of clay sand is the lowest.
