ABSTRACT:
A lightweight structural concrete with screw-ability and nail-ability similar to wood is composed of non-structural and ultra lightweight aggregate such as expanded perlite of a particular size distribution and amount, entrained air cells of another specific size distribution and amount, and dense cementitious composition of a cement binder, a fine grade structural filler no larger than masonry 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 that of wood.
