The weight of concrete can vary slightly depending on the mix type. The most typical value widely used is 150 lb/ft^3 for the most common/ordinary concrete strength at ~ 4,000 psi = 4000 lbf / (sq in). The aggregate used, strength of concrete and how thin or semi dry the concrete...
The specimens were cast with two normal weight and four lightweight self-consolidating concrete mixtures with compressive strengths of 4000 psi (27.6 MPa) at prestress transfer and 6000 psi (41.4 MPa) at 28-day of age or 6000 psi (41.4 MPa) at prestress transfer and 7000 psi (48.3 MPa) ...
normal weight 4000-psi concrete deck were fabricated. The girders were cast of concretes with a compressive strength of 6380 psi and a unit weight of 114 pcf. Full scale testing of the girders was conducted to evaluate development length and flexural strength in HPLWC composite girders. ...
Working Pressure: from 2bar (30psi) to 15bar (225psi) Temperature Range: from -5 to 65 degree C. Length/roll 50m/roll, 100m/roll or other. We support OEM/ODM order. Features:1. Made of pvc, reinforced with specialized industrial polyester yarn, h...
6000 psi (41 MPa) was selected as a lower strength limit for high strength concrete. According to the report, the selection was not intended to imply that there is a drastic change in mate- rial properties or in production tech- niques that occur at that particular ...
