Are you wondering if you can pour concrete an inch and a half thick? The answer is yes, but it is not recommended. The minimum thickness for pouring concrete is usually 1 to 2 inches. To ensure the best results, it is important to follow the right steps when pouring concrete. Before laying the concrete, it is important to moisten the surface and keep it moist until the concrete is placed.
Make sure there is no standing water on the slab during the laying process. To make a paste, mix together Portland cement and sand in a 50/50 ratio. To make a suspension, mix together water and latex bonding agent such as Acryl 60 in a 50/50 ratio. Before laying the concrete, use a stiff broom to clean or sweep away any existing grout on the floor.
Make sure the grout does not dry out before placing the concrete. When pouring concrete over existing concrete, the minimum thickness should be 2 to 2 ½ inches. Any thickness less than this could be too thin and lead to problems in the future. Before pouring new concrete, repair any cracks in the existing layer and separate the two layers.
If you are pouring concrete indoors, the cracks between the existing concrete and trenches for plumbing and electrical are unlikely to move. The most economical way to obtain concrete is to mix your own with Portland cement, sand and crushed stone. This will help ensure that you get strong concrete that will last for years without cracking or crumbling. When pouring concrete, avoid common mistakes such as using too much water or not using enough reinforcement.
Vapor barriers are used because fresh concrete should not stay wet for long periods of time. To ensure long-term reliability of your project, use corrosion-proof reinforcing rods and pour at least 2 inches thick with smaller aggregates and reinforcements such as welded wire mesh or fiber mixed into the concrete. Two weeks after pouring, use a masonry saw to make cuts to a third of the thickness of your slab concrete.
