Study on Strength Improvement of Pervious Concrete

PDF Roles of mortar volume in porosity, permeability and

the permeability of pervious asphalt concrete is influenced mainly by the porosity level of the asphalt concrete and the particle size and gradation of the sediment. Since pervious concrete tends to have lower strength than solid concrete, some researchers focused on the strength enhancement of pervious concrete [30-33].

Experimental Study on Recycled Aggregate Pervious Concrete

Pervious concrete has many advantages such as permeability to water, protection of water resources, and so on. This paper tests the recycled aggregate obtained by crushing high-strength waste concrete (TOU) and low-strength waste concrete (PU), and analyzes the effect of porosity, amount of cement, mineral admixture and recycled aggregate on

Sustainability | Free Full-Text | New Insights of Grouting

Pre-grouting as an effective means for improving the stability of roadways can reduce maintenance costs and maintain safety in complex mining conditions. In the Guobei coal mine in China, a cement pre-grouting technique was adopted to enhance the overall strength of soft coal mass and provide sufficient support for the roadway. However, there are very limited studies about the effect of

Fly Ash Concrete - What Are the Reasons for Adding Fly Ash

Higher strength, fly ash continues to combine with free lime increasing compressive strength over time. Increased durability, dense fly ash concrete helps keep aggressive compounds on the surface. Reduced shrinkage, the lubricating action of flyash concrete reduces water content and drying shrinkage.
