Can concrete stick to trex deck?
Some may wonder if you can lay Trex composite decking over concrete. The answer is yes but, first, we suggest you check with your local building office for any code requirements.
How can i make concrete dry faster?
Add warmer water. As one of the key ingredients in concrete, water is essential for the curing reaction to occur. The curing time can be hastened by using a slightly warmer water in the mixture as this will encourage the reaction to occur more quickly – do not, however, use blazing hot water as this could be damaging.

Is concrete stiffer than steel?
The compressive strength of concrete is more than the steel, to handle tension forces steel bars are used in the concrete because of the weakness of concrete. The wall made of concrete alone is much stronger than the mass of steel.
How to stick concrete to concrete?

How many expansion joints in a concrete slab?
Space joints (in feet) no more than 2-3 times the slab thickness (in inches). A 4″ slab should have joints 8-12 feet apart.
What is ductility in reinforced concrete?
Ductility is the ability of reinforced concrete members to undergo considerable deflection prior to failure. This characteristic of reinforced concrete structural members is crucial as it provides signs of failure and prevents total collapse. This is especially significant in seismic areas.
What causes cracks in concrete walls?
Shrinkage is a main cause of cracking. As concrete hardens and dries it shrinks. This is due to the evaporation of excess mixing water. The wetter or soupier the concrete mix, the greater the shrinkage will be.

Why does spraying concrete help it cure?
Known as “moist curing,” this allows the moisture in the concrete to evaporate slowly. Moist-cured concrete can be up to 50 percent stronger than concrete that was cured without being dampened!
What is a concrete pan bridge?
Pan-girder bridges were cast using self-supporting metal forms that spanned between bent caps. Multiple pans could be placed next to each other to form a concrete web. They were connected with bolts that passed through holes on the sides of the forms (Breña, 2001).
