Transverse Strength Test on Roofing Tiles Based on ASTM C 1167 and IS
The transverse strength test of roofing tile is commonly carried out based on the specifications of applicable standards such as ASTM 1167-11 and IS 13801. It involves wet or dry method test and conducted in the lab to estimate breaking ...
Water Absorption Test on Roofing Tiles
Water absorption test is the measurement of moisture quantity that roofing tile may absorb. If water absorption is too high, the tile may suffer from cracking which is not desirable. So, this test reflects the suitability of the tile for ...
Formwork -Technical, Functional, Economical, and Safety Requirements
There are several requirements that formwork structure need to meet otherwise it would not serve its purpose adequately. In order to make sure that the form structure fulfill its design goals, the designer and site engineer should take technical, functional, ...
How Coarse Aggregate Affects Mix Design of Concrete?
Coarse aggregate is one of the essential components of concrete and occupies the largest volume in the mix. That is why it greatly affects the concrete mix design. Its properties such as strength, maximum size, shape, and water absorption influence ...
6 Factors Affecting Lateral Pressure of Fresh Concrete on Forms
There are several factors that influence the magnitude of lateral pressure of fresh concrete on formwork sides. For instance, concrete weight, rate of placement, vibration, the temperature at the time of pouring, chemistry, and slump. Formwork designers need to take ...
How to Achieve Economy in the Cost of Formwork Construction?
The reduction of formwork construction is essential in declining the total cost of the project because it accounts for up to 60% of the entire cost of concrete structure. Decision made at the design phase can play crucial role in ...
