High-strength concrete has a compressive strength greater than 40 MPa (6000 psi). In the UK, BS EN 206-1 [3] defines High strength concrete as concrete with a compressive strength class higher than C50/60. High-strength concrete is made by lowering the water-cement (W/C) ratio to 0.35 or lower.
The product data submittal usually consists of the manufacturer's product information. The information included in this submittal are: Manufacturer, trade name, model or type number and quantities: This information is necessary to compare the submitted item with the specified products and acceptable products listed, in the specification and addenda.
A higher ratio gives a too fluid concrete mix resulting in a too porous hardened concrete of poor quality. Often, the concept also refers to the ratio of water to cementitious materials, w/cm. Cementitious materials include cement and supplementary cementitious materials such as ground granulated blast-furnace slag (GGBFS), fly ash (FA), silica ...

Concrete reinforcing is custom-fabricated from 60-foot-long reinforcing bars. [5] The reinforcing bars are cut to length and bent to specific configurations. The shop drawing and the accompanying “cut sheet” lists the quantity, sizes, lengths, and shapes of the reinforcing bar. [ 5 ]
Since flowable fill is normally a comparatively low-strength material, there are no strict quality requirements for fly ash used in flowable fill or controlled low strength material mixtures. Fly ash is well suited for use in flowable fill mixtures. Its fine particle sizing (nonplastic silt) and spherical particle shape enhances mix flowability.
