Problems solved by technology

However, the autoclaved aerated concrete block in the prior art has the following disadvantages: (1) the block steel is brittle and easy to break; (2) the block absorbs water quickly, which brings construction difficulties to the plastering of the wall, The walls are prone to cracking, hollowing, leakage and other technical problems; (3) Due to the gelation problem of the combination of various materials in the production of blocks, the product qualification rate is low, and waste products have become a new energy-saving and environmental protection problem

Abstract

The invention relates to the autoclaved aerated concrete block field, and discloses a silicate plasticizing powder enabling autoclaved aerated concrete blocks to have the characteristics of high product qualification rate, slow block water absorption and high compressive strength. The silicate plasticizing powder comprises a carrier, an anionic surfactant and a setting accelerator; the anionic surfactant comprises a first anionic surfactant and a second anionic surfactant; the mass of the first anionic surfactant is 14.0-0.25% of the mass of the carrier; the mass of the second anionic surfactant is 11.0-0.25% of the mass of the carrier; and the setting accelerator is 5%-0 of the mass of the carrier. The application of the above technical scheme in the embodiment of the invention makes the silicate plasticizing powder have the properties of negative ions, micro-bubbles and colloidal polar molecules, so the silicate plasticizing powder enables the autoclaved aerated concrete blocks to have the characteristics of high product qualification rate, slow block water absorption and high compressive strength.

Description

technical field [0001] The invention relates to the field of autoclaved aerated concrete blocks, and discloses a silicate plasticizing powder capable of making the autoclaved aerated concrete blocks have a high qualified rate, slow water absorption and high compressive strength. Background technique [0002] With the increasing development of science and technology, autoclaved aerated concrete block has become a new type of wall material for construction. This material needs to be cured by high temperature, high pressure and steam. However, the autoclaved aerated concrete block in the prior art has the following disadvantages: (1) the block steel is brittle and easy to break; (2) the block absorbs water quickly, which brings construction difficulties to the plastering of the wall, The wall is prone to cracking, hollowing, and leakage and other technical problems; (3) Due to the gelation problem of the combination of various materials in the production of blocks, the product ...
