Homogeneous porous matrix for ultra-light thermal insulation building material, self-thermal insulation concrete block and manufacturing method of self-thermal insulation concrete block
The invention relates to a homogeneous porous matrix for an ultra-light thermal insulation building material, a self-thermal insulation concrete block and a manufacturing method. Relates to the field of building materials. The mechanical property and the thermal property are excellent, and the cost is reasonable. The homogeneous porous matrix is prepared from the following components in parts by mass: 0.45 to 2.15 parts of foaming agent, 0.89 to 7.26 parts of additive, 0 to 1.6 parts of chopped fiber, 259 to 500 parts of water and 431 to 625 parts of inorganic composite cementing material, and the inorganic composite cementing material is prepared by mixing 55.5 to 89.94 parts of cement and 6.00 to 28.00 parts of mineral superfine powder with any one or two or more of 4.00 to 15.00 parts of desulfurized gypsum, 0 to 0.01 part of gypsum retarder and 0.06 to 1.40 parts of modifier. Wherein the ultra-light thermal insulation particles are used as ultra-light aggregate and a pore structure framework, and the homogeneous porous matrix is filled among the ultra-light thermal insulation particles and plays an adhesive and structural role; the dry apparent density, thermal insulation property, compressive strength, other physical and mechanical properties and durability of the self-thermal insulation concrete block are directly determined by the properties of the ultra-light thermal insulation particles and the homogeneous porous matrix and the volume ratio of the ultra-light thermal insulation particles and the homogeneous porous matrix.
