Weight of the concrete per volume of concrete. Automatic calculator for the specific unit weight of a volume of concrete in pcf, lb/ft^3, lb/yd^3, kg/m3, fresh wet concrete mix and dry cured hardened concrete. Weighing concrete in tonnes per cubic meter
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 tim...
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...
D. Concrete Panel Joint: Vertical
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...
A reduced weight, reduced density gypsum panel that includes high expansion vermiculite with fire resistance capabilities that are at least comparable to (if not better than) commer
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 ...
