An integral dual module geopolymer building block includes an inner foam module for insulation and an outer dense tile surface on an outer side of the inner foam module for weather protection. The outer porous module comprises a geopolymer paste including sodium silicate and sodium hydroxide flakes dissolved in the sodium silicate to form an activated solution and adding calcined kaolin clay to the activated solution to form a geopolymer paste. A first relatively dense tile layer has a thickness of about 0.5 cm to 1.5 cm. A second geopolymer layer made from a second mass of paste mixed with hydrogen peroxide forms a geopolymer foam having a thickness of between 5 cm and 15 cm.

Disclosed is a fire-proof thermal-insulation board of aerated concrete of B02-level lightweight autoclaved sand and its preparation method. Components of the thermal-insulation board are quartz sand, lime, cement, gypsum, aluminum powder, and foam stabilizer, weight percentages of the components are: 56%60% of the quartz sand, 8%11% of the lime, 20%30% of the cement, 2%4% of the gypsum, 0.24%0.26% of the aluminum powder, and 0.02%0.03% of the foam stabilizer. The fire-proof thermal-insulation board is made of an inorganic non-metallic material with lightweight, non-inflammable property and good thermal-insulation performance. The present disclosure well solves the thermal bridge problem of external wall of the building, and has A1-level fire-proof performance and good durability with the same service life as the building. The present disclosure overcomes low product strength, and inconvenience in transportation and construction in the prior art, reduces types of admixture used in the manufacturing process, and reduces the manufacturing cost.
