科学合理处理建筑垃圾,使用再生骨料,不仅可以减少建筑业对天然骨料的消耗,还可以减少固体废弃物造成的环境污染问题。研究再生骨料物理力学性能意义重大。本文通过四个方案研究再生骨料的堆积密度问题,找出其与天然骨料的区别与联系。1.试验目的及依据本次试验的目的是测定四种不同比例再生骨料的堆积密度,分别为100%再生细骨料,30%再生细骨料70%天然那砂,60%再生细骨料40%天然砂,100天然砂。为以下试验提供技术依据。本试验依据GB/
Scientific and reasonable treatment of construction waste, the use of recycled aggregate, not only can reduce the natural aggregate consumption of construction, but also reduce the environmental pollution caused by solid waste. It is of great significance to study the physical and mechanical properties of recycled aggregates. In this paper, the four programs to study the bulk density of recycled aggregate problem, find out the difference between natural aggregates and contact. 1. Purpose and basis of the test The purpose of this test is to determine the bulk density of four different proportions of recycled aggregate, respectively, 100% recycled fine aggregate, 30% recycled fine aggregate 70% natural sand, 60% regenerated fine bone Material 40% natural sand, 100 natural sand. Provide the technical basis for the following test. The test based on GB /
