Gobi aggregate concrete and preparation method thereof
The invention discloses gobi aggregate concrete and a preparation method thereof, each cubic meter of gobi aggregate concrete comprises 450kg of cement, 714kg-816kg of composite sand, 1222kg-1428kg of gobi gravel, an additive and water, the water-cement ratio of the gobi aggregate concrete is 0.58, and the sand ratio is 35%; the composite sand comprises natural river sand and gobi sand, the mass ratio of the natural river sand to the gobi sand is 1: 1, the gobi sand and the gobi broken stone are subjected to continuous particle size grading, the particle size range of the gobi sand is 0-4.75 mm, the fineness modulus is 2.8, the silt content is 2.8%, the particle size range of the gobi broken stone is 4.75-31.5 mm, and the silt content is 1.8%; the mass of the admixture is 5% of the mass of the cement, and the admixture comprises 45 parts by mass of a polycarboxylic acid water reducer, 16 parts by mass of cellulose grafted chitosan, 16 parts by mass of flue sediment, 6 parts by mass of a silane coupling agent, 3 parts by mass of polyvinylpyrrolidone and 2 parts by mass of silicon carbide. The invention solves the problem that the current gobi aggregate cannot realize effective resource utilization.
本发明公开了一种戈壁集料混凝土及其制备方法，每立方戈壁集料混凝土包括450kg的水泥、714kg～816kg的复合砂、1222kg～1428kg的戈壁碎石、外加剂和水，戈壁集料混凝土的水灰比为0.58，砂率为35％；复合砂包括天然河砂和戈壁砂，天然河砂与戈壁砂的质量比例为1：1，戈壁砂和戈壁碎石进行连续粒级级配，戈壁砂的粒径范围为0mm～4.75mm，细度模数2.8，含泥量为2.8％，戈壁碎石的粒径范围为4.75mm～31.5mm，含泥量为1.8％；外加剂的质量为水泥的质量的5％，外加剂包括45质量份的聚羧酸系减水剂、16质量份的纤维素接枝壳聚糖、16质量份的烟道沉积物、6质量份硅烷偶联剂、3质量份聚乙烯吡咯烷酮和2质量份的碳化硅。本发明解决了目前的戈壁集料未能实现有效资源化利用的问题。
