Abstract
A soil solidification material based on solid waste and bioenzyme, and a preparation method thereof are disclosed. The soil solidification material is composed of the following components in parts by weight: recycled aggregate 22-35 parts, steel slag 20-30 parts, high-calcium fly ash 16-24 parts, the bioenzyme 5-15 parts, an inorganic adsorbent 10-18 parts, an organic adsorbent 8-20 parts, industrial waste gypsum 25-35 parts, an activator 20-30 parts, sodium citrate 1-3 parts, and slaked lime 0.02-0.2 parts. The present disclosure adopts the recycled aggregate, the steel slag, the industrial waste gypsum and the high-calcium fly ash as the main components of the soil solidification material to reduce the cost. The soil solidification material of the present disclosure prepared by optimizing the proportion is capable of significantly improving the engineering properties of the soil or the mixed contaminated soil, and has significant economic and environmental benefits.
