Preparation method of fiber light aggregate concrete slab and concrete slab prepared by preparation method
The invention discloses a preparation method of a fiber light aggregate concrete slab and the concrete slab prepared by the preparation method, and the preparation method comprises the following steps: step 1, weighing 50-150 parts by mass of a light aggregate, and carrying out pre-wetting treatment on the light aggregate to prepare a pre-wetted light aggregate; 2, stirring 100-150 parts by mass of cement, 30-50 parts by mass of limestone powder, 0.5-3 parts by mass of a water reducing agent and 2-5 parts by mass of a binder in a stirring pot for 10-15 min to prepare a mixture A; and 3, addingthe pre-wetted light aggregate obtained in the step 1 into the mixture A obtained in the step 2, and stirring for 3-5 minutes to obtain a mixture B; and the fibers can be fully dispersed into monofilaments without pre-dispersing the fibers, so that the operation steps are reduced, and the fiber dispersion effect is good.
本发明公开了一种纤维轻集料混凝土板制备方法及其制得的混凝土板，包括以下步骤：步骤一，按照质量份数，称取50～150份轻集料，并对轻集料进行预湿处理，制得预湿轻集料；步骤二，按照质量份数，将100～150份水泥、30～50份石灰石粉、0.5～3份减水剂和2～5份粘结剂置于搅拌锅中搅拌10～15min，制得混合料A；步骤三，将步骤一的预湿轻集料加入至步骤二的混合料A中搅拌3～5min，制得混合料B。无需预分散纤维，也能使纤维充分分散成单丝，减少了操作步骤，且纤维分散效果佳。
