Modified polyphenyl granule lightweight concrete and preparation method thereof
The invention discloses modified polyphenyl granule lightweight concrete and a preparation method thereof. The modified polyphenyl granule lightweight concrete has good physical and chemical properties. The lightweight concrete is prepared from the following components in parts by weight: 450 to 500 parts of cement, 450 to 500 parts of coal cinder, 300 to 350 parts of coal ash, 5 to 8 parts of redispersible latex powder, 2 to 5 parts of polypropylene fiber, 3 to 5 parts of hydroxypropyl methyl cellulose, 2 to 4 parts of FND superplasticizer, 2 to 4 parts of defoaming agent, 20 to 30 parts of polyphenyl granules and 380 to 430 parts of water. The preparation method comprises the following steps: (10) adding the water, the redispersible latex powder, the hydroxypropyl methyl cellulose, the FND superplasticizer and the defoamer, and uniformly stirring to obtain a mixture A, (20) adding cement and fly ash into A, and stirring for 5-8 minutes to obtain a mixture B, and (30) adding the modified polyphenyl granules, polypropylene fibers and coal cinder into B, and stirring to obtain the modified polyphenyl granule lightweight concrete.
本发明公开一种改性聚苯颗粒轻质混凝土及其制备方法，理化性能好。所述轻质混凝土的组成及重量份数为：水泥450‑500份，煤渣450‑500份，粉煤灰300‑350份，可再分散性乳胶粉5‑8份，聚丙烯纤维2‑5份，羟丙基甲基纤维素3‑5份，FND高效减水剂2‑4份，消泡剂2‑4份，聚苯颗粒20‑30份，水380‑430份。制备方法包括以下步骤：(10)先加入水、可再分散性乳胶粉、羟丙基甲基纤维素、FND高效减水剂和消泡剂，搅拌均匀，得到混合物A；(20)在A中加入水泥和粉煤灰，搅拌5‑8min，得到混合物B；(30)在B中加入改性聚苯颗粒、聚丙烯纤维及煤渣，搅拌得到改性聚苯颗粒轻质混凝土。
