Lightweight structural concrete provided with various wood properties
Abstract:
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.
