Geopolymer composite material and preparation method thereof
The invention belongs to the technical field of engineering materials, and discloses a geopolymer composite material and a preparation method thereof. The geopolymer composite material is prepared from the following raw materials in parts by mass: 120-180 parts of a mineral admixture; 0.5 to 3 parts of sodium alginate; 180 to 280 parts of an alkali activator; the mineral admixture is metakaolin. The preparation method of the geopolymer composite material comprises the following steps: mixing a mineral admixture, sodium alginate and an alkali activator to obtain mixed slurry, pouring the mixed slurry into a mold, and carrying out sealed maintenance, demolding and continuous maintenance to obtain the geopolymer composite material. By adding the sodium alginate, the mechanical strength of the geopolymer composite material is effectively improved, the geopolymer composite material has higher compactness, the initial setting time and the final setting time of the composite material are shortened, the early strength is remarkably improved, engineering application is facilitated, and good economic and social benefits are achieved.
本发明属于工程材料技术领域，公开了一种地聚物复合材料及其制备方法。本发明所述地聚物复合材料，由以下质量份数的原料制备而成：矿物掺合料120～180份；海藻酸钠0.5～3份；碱激发剂180～280份；所述矿物掺合料为偏高岭土。本发明所述地聚物复合材料的制备方法，包括以下步骤：将矿物掺合料、海藻酸钠及碱激发剂混合，得到混合浆体，将混合浆体倒入模具，密封养护，脱模，继续养护，得到地聚物复合材料。本发明通过添加海藻酸钠，有效提升了地聚物复合材料的力学强度，具有更高的密实度，缩短了复合材料的初凝、终凝时间，且显著提升早期强度，便于工程应用，具有良好的经济、社会效益。
