WebApr 8, 2024 · Date palm fiber (DPF) has been reported to have many advantages when used in concrete, however, its major disadvantage is that it causes a reduction in compressive strength. In this research, powdered activated carbon (PAC) was added to cement in the DPF-reinforced concrete (DPFRC) to lessen the loss in strength. PAC has … WebX-Ray Mass Attenuation Coefficients 3. The Mass Energy-Absorption Coefficient, μ en /ρ The methods used to calculate the mass energy-absorption coefficient, μ en /ρ, are described perhaps more clearly through the use of an intermediate quantity, the mass energy-transfer coefficient, μ tr /ρ. The mass energy-transfer coefficient, μ tr /ρ, when …

WebConcrete absorbs water, particularly if it is a slab on moist soil or if there is a leaky pipe embedded in the concrete. Water also comes from condensation or from rainfall if the … WebConcrete Shines as Solar Reflectance Material. Concrete does a very good job of reflecting solar energy. That is the finding from a Portland Cement Association (PCA) study which measured the solar reflectance index (SRI) of 45 concrete mixes. Lighter colored materials (such as concrete) generally have a higher solar reflectance. WebThe compressive strength of concrete was 53 MPa and the yield strength of longitudinal and transverse reinforcing steels was 500 MPa. Constant column and beam dimensions were utilized throughout the building. ...
