Paper Title:
Research on Influences of Activity Mineral Admixture on Workability and Mechanical Properties of High Strength Lightweight Aggregate Concrete
  Abstract

Aiming at the high expense of high strength lightweight aggregate concrete (HSLWAC), low-cost HSLWAC was produced making use of the industrial wastes including fly-ash (FA) and ground granulated blast furnace slag (GGBS) as admixture, and the influences of these admixtures on the workability and mechanical properties of HSLWAC were studies. Result shows that HSLWAC whose cubic compressive strength is high to 70MPa at the age of 28d can be produced with mixing admixtures; the effect of mixing GGBS to the strength of HSLWAC is better than that of mixing FA; and mixing admixtures is useful for the improvement of the workability of HSLWAC; However, the brittleness of HSLWAC rises with the increase of its strength.
