Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb/ ft3 (1440 to 1840 kg/m3) compared to normalweight concrete with a density in the range of 140 to 150 lb/ ft3 (2240 to 2400 kg/m3).
High Performance Concrete. High Performance Concrete (HPC) refers to concrete with a specified compressive strength of 6,000 psi and greater. By carrying loads more efficiently than normal-strength concrete, high-strength concrete can reduce the total amount of material placed and lowers the overall cost of the structure.
They are then embedded in high-performance concrete with the structural density that protects the fibers almost completely against weathering. This weave is also modified with natural resins ...
For LBM dealers, structural steel's supply chain is much more accessible than that of precast concrete, except that steel's use has fluctuated downward with recent commodity prices while precast's popularity is growing steadily among home builders.
Design a lightweight, high-performance concrete mixture, proportioned according to the American Concrete Institute Manual of Concrete Practice, ACI 211.2, Standard Practice for Selecting Proportions for Structural Lightweight Concrete.
