Permeability of Fibre Reinforced Mortar under Compression
interconnectivity of the cracks and in turn increases permeability of concrete ... SP 1% Of Mortar Cement Fibre (PP) 0.25% of Mix Volume 23. Load levels •Load levels: 0, 25%, 50%, 75% & 90% of ultimate load •Ultrasonic wave velocities were also performed on the same load levels as above
Fiber Cement Siding vs. Stucco
Stucco is also restricted in its ability to move and breath, which can cause issues such as cracks to appear in its surface. Once these cracks appear, more moisture can make its way inside, causing even more damage. Fiber cement siding performs well with moisture. Fiber cement technology produces an extremely durable, weather-resistant siding.
Best Concrete Crack Filler (2020): Reviews and Comparison
Mar 24, 2020 · Unless you’re experienced in repairing concrete cracks, the ease of use should be an important factor while selecting the best concrete crack filler to meet your requirements. Some crack fillers need a lot of prep, including mixing and heating. If the proportion of the mix is not accurate, it could affect the quality of the repair.
