一种轻骨料混凝土及其制备方法
摘要：
本发明公开了一种轻骨料混凝土及其制备方法，涉及混凝土领域，该混凝土由以下原料按照如下质量配比制成：水泥：粉煤灰：轻骨料：砂：水：聚羧酸减水剂＝1：(0.00-0.14)：(1.53-1.66)：(1.27-1.45)：(0.28-0.34)：(0.085-0.01)，该混凝土的制备方法包括以下步骤：按质量份数计，将1.53～1.66份轻骨料放入水中浸泡24h后取出，晾至轻骨料内部孔隙至饱和面干，得到预混轻骨料，向预混轻骨料中加入1.27～1.45份砂和1份水泥，混合均匀后，加入0.28～0.34份水和0.085～0.01聚羧酸减水剂，搅拌90秒后出料，得到轻骨料混凝土。本发明能够提高轻骨料混凝土的抗压强度，降低轻骨料混凝土的容重。
摘要（英）：

The invention discloses lightweight aggregate concrete and a preparation method thereof and relates to the field of concrete. The concrete is prepared from cement, coal ash, lightweight aggregate, sands, water and polycarboxylate superplasticizer in a mass ratio of 1: (0.00-0.14): (1.53-1.66): (1.27-1.45): (0.28-0.34): (0.085-0.01). The preparation method of the concrete comprises the following steps: putting 1.53-1.66 parts by mass of lightweight aggregate in water for 24 hours and taking out the lightweight aggregate; airing till internal holes of the lightweight aggregate till the saturated face is dried to obtain premixed lightweight aggregate; adding 1.27-1.45 parts of sands and 1 part of cement into the premixed lightweight aggregate; uniformly mixing; adding 0.28-0.34 part of water and 0.085-0.01 part of polycarboxylate superplasticizer; stirring for 90 seconds and discharging to obtain the lightweight aggregate concrete. According to the invention, the compression strength of the lightweight aggregate concrete can be enhanced and the capacity of the lightweight aggregate concrete can be reduced.
