摘 要:為研究礦物摻合料對泡沫混凝土力學性能、導熱系數、抗凍性的影響,以粉煤灰摻量10%的泡沫混凝土為基準,通過分別單摻硅灰和礦粉及復摻硅灰、礦粉研究了礦物摻合料對泡沫混凝土性能的改善作用。結果表明:當分別單摻硅灰和礦粉時,泡沫混凝土的抗壓強度、抗折強度及抗凍性均得到一定提升,導熱系數隨之增大;當復摻硅灰和礦粉,且復摻比例為2∶1時,泡沫混凝土的強度和抗凍性最佳,導熱系數最大。
Abstract: To study the influence of mineral admixtures on the mechanical properties, thermal conductivity, and frost resistance of foamed concrete, based on the foamed concrete with a fly ash content of 10%, by mixing silica fume and mineral powder alone and compounding silica fume and mineral powder respectively, the improvement effect of mineral admixture on the foamed concrete was studied. The results show that when silica fume and mineral powder are added separately, the compressive strength, flexural strength and frost resistance of foamed concrete are improved to a certain extent, and the thermal conductivity increases accordingly. When silica fume and mineral powder are added, the compressive strength, flexural strength, and frost resistance of foamed concrete are increased. When the mixing ratio of silica fume and slag powder is 2∶1, the strength and frost resistance of the foamed concrete are the best, and the thermal conductivity is the largest.
