摘　　要：以强度和表观密度为指标，以粉煤灰掺量、矿粉掺量、砂率作为因素，每个因素取三个水平采用正交试验方法进行矿物掺合料高性能轻骨料混凝土研究。通过试验，得出各因素的主次顺序，并根据包头本地原材料的特点得出高性能轻骨料混凝土的最佳配比。As indicators of strength and apparent density, as factors of fly ash, slag ash, sand ratio; taking three level orthogonal test methods for the mineral admixture high-performance lightweight aggregate concrete each factor. Test obtained that the primary and secondary order of the factors, and the best ratio of high-performance lightweight aggregate concrete at the basis of the characteristics of the Baotou local raw materials.
