Embodiment 1
[0020] A high-stability accelerator for concrete is characterized in that it is made of the following raw materials in parts by weight: 40 parts of polyglutamic acid, 5 parts of adsorbent, 5 parts of calcium sulfate, 2 parts of polyaspartic acid, 3 parts of emulsifier, 2 parts of sodium gluconate, 1 part of crospovidone, 2 parts of aluminum oxide, 2 parts of ascorbic acid, 2 parts of potassium methyl silicate, 0.2 part of sodium lauryl sulfate.
[0021] The adsorbent is made of zeolite powder, activated carbon powder, rice straw, and alum according to the mass ratio of 1:1:1.5:0.5, and the production method is as follows: put the rice straw into a drying oven at 120° C. More than 2%, crushed into 40-mesh powder, add appropriate amount of water and stir evenly until muddy paste, then put into carbonization furnace at 400°C for carbonization for 1 hour, take it out and cool, and crush into 60-mesh powder to obtain carbonized powder; dissolve alum in Appropriate amount of water, ...
