| 摘 要： | 将湖北襄阳地区的建筑垃圾粉碎筛分得到再生砂,以再生砂部分或全部取代建筑砂浆中的天然砂,用粉煤灰作为掺加料,制作再生砂浆,研究再生砂对砂浆和易性及抗压强度的影响.在砂浆流动性基本相同的情况下,随再生砂掺量增加,砂浆的用水量明显增大、保水性趋于提高.再生砂浆在再生砂取代量为40%时获得良好的骨料级配,强度提高.

| Abstract: | Construction waste in HuBei Xiangyang region can be recycled by screening the crushed sand,part or all of the recycled sand to replace natural sand in constuction mortar,with fly ash extract as admixture to produce recycled aggregate mortar.It is researched on the influence of recycled sand on mortar workability and compressive strength.Under the same circumstances of mortar liquidity,with the recycled sand content increased,mortar's retention tends to increase and water's dosage tends to increase too.When ... |
