It was found that the strength of no-fines concrete is strongly related to its mixture proportion and compaction energy. A sealed compressive strength of 20.7 MPa (3,000 psi) can readily be achieved with an aggregate cement ratio of 4.5:1 or less and a minimum compaction energy of 165 Jm3...
1) no-fines 无砂 1. It introduced the mix proportion and performance of no-fines pervious concrete,and the concrete which is of high strength,large porosity ratio and good water permeability was used in the Beijing North-South Long Street road engineering. 对无砂透水混凝土的配合比与性能...
Two main variables were considered, namely, the fibres volume fraction which was taken in the range of 0.0-1.5% and the fibres aspect ratio (8.16 and 24). It has been shown that the addition of waste-plastic fibres to the no-fines light-weight concrete mix succeeded in increasing both ...
It was found that the strength of no-fines concrete is lower that that of normal weight concrete, but sufficient enough for structural use. Due to its high ratio of continuous voids, this concrete has high water permeability.MEHETRE DINESH S...
