The invention provides a baking-free brick. The baking-free brick is prepared from the following raw materials in parts by weight: 800-1000 parts of building residue soil; 200-300 parts of rice fieldstraw; 80-120 parts of cement; 22-30 parts of slaked lime; 25-35 parts of gypsum; 8-12 parts of a curing agent; 3-5 parts of an active agent; 1-3 parts of a weather-resistant agent; 100-150 parts of water. Sodium lignosulfonate is a natural high-molecular polymer and an anionic surfactant, has very strong dispersing capacity, and is suitable for dispersing solids in an aqueous medium. The sodium lignosulfonate can be adsorbed on the surface of various solid particles and can be used for metal ion exchange. The sodium lignosulfonate is used as a dispersing agent and a wetting agent, and is mixed with a soil body to generate a series of physical and chemical reactions, and a thin layer of water film wrapping the surface of each fine particle is removed so that the engineering property of thesoil body is changed, and the strength and the water resistance of the baking-free brick are effectively improved.
本发明提出一种免烧砖，由以下原料按照重量份组成：建筑渣土800‑1000份；稻田秸秆200‑300份；水泥80‑120份；消石灰22‑30份；石膏25‑35份；固化剂8‑12份；活性剂3‑5份；抗风化剂1‑3份；水100‑150份。木质素磺酸钠是一种天然高分子聚合物，阴离子型表面活性剂，具有很强的分散能力，适于将固体分散在水介质中。能吸附在各种固体质点的表面上，可进行金属离子交换作用，木质素磺酸钠用作分散剂和润湿剂，与土体混合后产生一系列物理化学反应，将裹在每一个细微颗粒表面薄薄的一层水膜去掉，从而改变土体的工程性质，有效提高免烧砖的强度和耐水性。
