High-strength foam cement light soil and preparation method thereof
The invention discloses a preparation method of high-strength foamed cement light soil, and relates to the field of light soil. The preparation method of the high-strength foamed cement light soil comprises the following steps: adding hydrogen peroxide, a foam stabilizer and a water reducing agent into water, and uniformly mixing to obtain a mixture A; adding the cement and the admixture into water, uniformly stirring to obtain a premix, adding the iron powder into the premix, and uniformly mixing to obtain a mixture B; dissolving sodium alginate in water to obtain a mixture C; adding the mixture B into the mixture C, and uniformly stirring to obtain a mixture D; uniformly mixing the mixture D and the mixture A to obtain slurry, pouring the slurry into a mold, and curing to obtain the high-strength foam light soil. The foamed cement light soil not only has lower dry density, but also has higher compressive strength, smaller drying shrinkage value and better impermeability.
本申请公开了一种高强度泡沫水泥轻质土的制备方法，涉及轻质土领域。高强度泡沫水泥轻质土的制备方法包括以下步骤：将双氧水、稳泡剂、减水剂加入水中均匀混合，得到混合物A；将水泥、掺和料加入水中，搅拌均匀后得到预混物，往预混物中加入铁粉，均匀混合得到混合物B；将海藻酸钠溶于水中，得到混合物C；往混合物C中加入混合物B，搅拌均匀，得到混合物D；将混合物D与混合物A均匀混合得到料浆后，将料浆倒入模具中，养护，得到高强度泡沫轻质土。该泡沫水泥轻质土不仅具有较低的干密度，还具有具有较高的抗压强度、较小的干燥收缩值以及较好的抗渗性能。
