A process for producing foamed concrete includes introducing air pores into aqueous concrete compositions by one or more air pore formers and/or by introducing air. The aqueous concrete compositions are based on one or more foam stabilizers, one or more protective colloid-stabilized polymers of ethylenically unsaturated monomers in the form of aqueous dispersions or water-redispersible powders, 30% to 95% by weight of cement, based on the dry weight of the components for production of the concrete compositions, optionally one or more fillers, and optionally one or more additives.

The invention is directed to compositions, tools and methods for the manufacture of construction materials, masonry, solid structures and compositions to facilitate dust control. More particularly, the invention is directed to the manufacture of bricks, masonry and other solid structures using small amount of aggregate material that is pre-loaded with spores and/or vegetative bacterial cells.

A soil solidification material based on solid waste and bioenzyme, and a preparation method thereof are disclosed. The soil solidification material is composed of the following components in parts by weight: recycled aggregate 22-35 parts, steel slag 20-30 parts, high-calcium fly ash 16-24 parts, the bioenzyme 5-15 parts, an inorganic adsorbent 10-18 parts, an organic adsorbent 8-20 parts, industrial waste gypsum 25-35 parts, an activator 20-30 parts, sodium citrate 1-3 parts, and slaked lime 0.02-0.2 parts. The present disclosure adopts the recycled aggregate, the steel slag, the industrial waste gypsum and the high-calcium fly ash as the main components of the soil solidification material to reduce the cost. The soil solidification material of the present disclosure prepared by optimizing the proportion is capable of significantly improving the engineering properties of the soil or the mixed contaminated soil, and has significant economic and environmental benefits.
