Steel fiber; Ends-structure; Volume ratio; Mechanical properties; Anchor Abstract In this paper, we study the effects on mechanical properties of cement mortar with different types of steel fibers. The results showed that: Among the three kinds of cement mortars mixed with different steel fibers,...
In recent years, the jet-grout (JG) technique has been one of the most preferred soil improvement methods. The specimen column diameter-length, grouting pressure, rod linear-rotational speed, nozzle diameter-number, water/cement ratio, cement properties, and soil properties are the main factors a...
The plasticity of new concrete permits the creation of limitless shapes, designs, and finishes. Depending on the look that one desires and the type of concrete finish floor, specialized tools are used, which can turn any simple cement finish floor into gorgeous-looking flooring. Benefits of concr...
The coating prevents water molecules from making excellent contact with the cement particles by acting as a diffusion barrier. i) Phosphonates ii) Lignosulphonates iii) Sugars iv) Hydroxycarboxylic acids and their salts i) Salts of Pb, Zn, Cu, As, Sb ii) Borates iii) Phosphonates Fig 2:...

Concrete is a building material made of cement, aggregates (rock and sand), water, and additives (chemicals that enhance or modify the properties of concrete). There are a lot of chemicals used in construction now. From concrete admixtures to sealants, grouts, bonding agents, and waterproofing...
In the case of jasper and greenstone, the long-term properties were analyzed by LA tests where the number of rotations were increased from 100 to 900 (Erichsen 2015). Similar tests were introduced based on the slake durability index, which is used to test weak and clay-bearing rocks. ...

When installed we asked for the cement to be whiter in color compared to the more grey standard and they said they achieved this by adding a higher proportion of cement to the mix. Questions are, could the whiter mix be the reason for this? What else could it be? We live in a very...
