Abstract: 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.

Abstract: An interlocking and insulated construction block includes a first pair of parallel, opposing sides and a second pair of parallel, opposing sides extending normal to the first pair of opposing sides. At least one cavity or recess extends through the construction block and includes a first volume of thermal insulation material. One or both sides of the first pair of opposing sides includes a pair of staggered engaging members or a pair of staggered receiving members configured to engage or lock with a mating pair of engaging members or receiving members of another insulated construction block. A plurality of different embodiments of the interlocking and insulated construction blocks may be provided in a set, and provide for mortar-less construction of walls due to their interlocking nature.
