摘要
通过对水灰比、砂灰比、压浆助剂、膨胀剂等影响混凝土强度因素的逐一研究,在综合采用以上各项技术的基础上,配制的压浆混凝土强度达到 30MPa以上。
The factors that influence the strength of pre-placed aggregate concrete such as water-cement ratio, sand-cement ratio, additives, expansive admixture and so on are studied. The pre-placed aggregate concrete with 30Mpa strength is produced with a combination of techniques in view of these factors.
