Abstract

The invention discloses an inorganic heat insulation load-bearing concrete, belonging to the technical field of heat preservation load-bearing concrete. The invention aims at solving the problem of providing a concrete which not only can meet the requirements of stress performance of structural components of buildings, but also has good heat preservation property. The adopted scheme comprises: the concrete comprises the components with mix proportion by weight (kg/m<3>): the ratio among composite lightweight doped-aggregate, cement, sand, carpolite, ceramsite, pulverized fuel ash, water and admixture is (6-225): (200-800): (300-700): (500-1600): (150-650): (10-600): (80-400): (0.1-200); wherein the composite lightweight doped-aggregate is one or mixture of more in vitrified micro-bead, vermiculite, expanded perlite and modified expanded perlite, and has the density of (50-180)kg/m<3>. Therefore, the load-bearing concrete can be widely applied to the field of building technology.
