Abstract:
1. A high strength lightweight concrete with two effective void size distributions in its matrix comprising: (a) an amount of coarse structural aggregate sized between ¼″ to ¼″ effective to achieve between 15% to 25% of a total concrete volume; (b) an amount of large size non-structural aggregate effective to achieve 8% to 20% of the total concrete volume, with a particle size distribution mean between 1 mm to 2.5 mm and with at least 75% of the amount of particles falling within a range of±0.6 mm from a center of the particle size distribution mean; (c) an amount of small size non-structural aggregate effective to achieve 5% to 15% of the total concrete volume, with a particle size distribution mean no larger than 70% of the particle size distribution mean of the large size non-structural aggregate; (d) a dense cementitious composition effective to achieve remaining 40% to 50% of the total concrete volume.
