    摘要: An improved concrete is provided having a concrete formed from a wet concrete mixture; and a non-chemical admix added to the wet concrete mixture and configured to contain bubbles in order to control the amount of entrained air formed in the concrete when the wet concrete mixture cures into the improved concrete. The non-chemical admix includes a multiplicity of hollow objects, bodies, elements or structures, each configured with a respective cavity, unfilled space, or hole to trap and maintain a bubble inside. The hollow objects, bodies, elements or structures include hollow cylinders, or spheres, or capillary tubes, or some combination thereof. Each hollow object, body, element or structure is configured with a dimension so as not to absorb liquid, including water, including where the dimension is in a range of about 20-30 microns, and is made of glass or a glass-like material.

    摘要: A lightweight structural concrete with screw-ability and nail-ability similar to wood-is composed of a non-structural and ultra lightweight aggregate such as expanded perlite or a combination of expanded perlite and polystyrene beads of a particular size distribution and volume amount, entrained air cells of another specific size distribution and volume amount, and dense cementitious composition of a cement binder, a fine grade structural filler no larger than concrete sand grade, a pozzolan, and optional micro-fibers for reinforcement. This structural concrete matrix is optimized to hold 13 gauge T-nails and bugle head wood screws with thread ranging from 8 to 11 threads per inch and diameter of 0.10" to 0.137". The resulting concrete will have consistent screw-ability and nail-ability similar to that of wood.
