Shear Strength of Stud Connectors in Lightweight and Normal-Weight Concrete JORGEN G. OLLGAARD, ROGER G. SLUTTER AND JOHN W. FISHER STEEL-CONCRETE composite construction using normalweight concrete has been used since early in the 1920's. Substantial use of composite construction began mainly for...
PURPOSE:To remarkably reduce the weight of concrete by blending the concrete with at least a mixed polymer emulsion based on an acrylic ester copolymer, sintered Shirasu (volcanic glass) balloons and fly ash. CONSTITUTION:This lightweight concrete contains at least a mixed polymer emulsion based on...
2. I seem to recall seeing test reports on concrete block that show compressive strength of normal weight and light weight block about equal. Your spec. should ask for submittal of test data on the block the contractor will use. You can actually get this from the block supplier at the ...

ACI-209 estimated creep of the 55.2 MPa lightweight concrete and shrinkage of the 69.0 MPa concrete within 20% accuracy, but greatly underestimated shrinkage of the 55.2 MPa mix. When compared with normal weight, high strength concrete of similar strength and similar cement paste content from ...
Prestressed concrete bridge girders can be designed with lightweight concrete that has compressive strengths of 6000 psi and 7500 psi and unit weights of 118 pcf to 122 pcf, respectively. Comparisons of AASHTO Type IV girders made from normal weight concrete and girders made from lightweight ...
For a new multistory concrete building, I am placing a 4” thick lightweight concrete topping on top of the normal weight structural slab at various locations (the required “depressed” area accounts for 70-80% of the floor plate, hence the entire structural floor is set at 4” down and...
In some embodiments, the high expansion particle distribution avoids instances of large concentrations of the high expansion particles in portions of the panel core that significantly reduce the structural strength and integrity of the core during normal use of the panels or during high temperature and...
