Abstract

The invention relates to a manufacturing method for a building material. The manufacturing method comprises the following steps: adding 2.66-8.76 parts by weight of spun-bonded non-woven fabric, 4.12-6.78 parts by weight of sodium alginate and 1.98-4.02 parts by weight of polyvinylpyrrolidone into a second intermediate product obtained in a step 2, carrying out stirring by a stirrer for 0.25-0.45hour, and then carrying out grinding to obtain powder; and sequentially adding 1.04-5.26 parts by weight of calcium aluminate, 1.02-4.24 parts by weight of an additive, 1.02-4.24 parts by weight of ananti-sagging agent and 1.02-4.24 parts by weight of an additive into the ground powder in a step 3, carrying out stirring for 0.25-0.45 hour, so as to obtain an adhesive complementary material. Withthe combination of other steps and methods, the defects that in the prior art, the adhesive performance of low-calcium silicate cement is poor, and the adhesion of the low-calcium silicate cement is not firm are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a method for manufacturing building materials. Background technique [0002] Due to the difference in structure, the activity of belite and water reaction is much lower than that of alite, which leads to the low early strength of low-calcium portland cement as a building material, such as traditional low-calcium portland cement (also called low-calorie cement) Portland cement) is mainly used in large-volume concrete projects such as hydraulic dams that do not require high early strength. Due to the low early strength of low-calcium Portland cement, it is difficult to meet the needs of high-speed construction of civil engineering, which restricts the application of low-calcium Portland cement in construction projects. [0003] So just released a kind of preparation method of low-calcium portland cement, comprises the following steps: [0004] Select low-calcium Portland cement...
