Oahu concrete contractors are a good source to help expand your knowledge of these processes. Until then let this article help expand your knowledge. The requirements of materials depend upon the type of concrete job under construction.
The materials for concrete itself are cement water and sand. They should be mixed in the right amount to get the standard viscosity and stickiness in the concrete.
Driveways and Patios:
For driveways patios and decorative projects on the ground, a woodenware frame is required in which the prepared concrete mixture will be poured. For decorative purposes acidic agents, color mixtures are required. Shovels and hoes are also required for the movement of concrete to the desired site.
Sidewalks and Slabs:
For sidewalks or slabs, forming is required. It requires digging up the area and leveling it by removing debris and sod. The area should be of the same level of depth. To make it perfect it is recommended to recess the area in accordance with the desired depth. Also, it is important to keep the ground moist.
One of these things are taken care of, the form is then constructed by 2 by 6’s formula. The stakes on the backside of the forms are then placed in the ground 3 to 4 feet apart from each other. The stakes are then cut off by the form boards and fastened with the form boards using duplex nails. Once the form is in place, it is then observed for its uniform level above the ground.
The reinforcement material is required for driveways and patios and garages. The concrete can be reinforced by using steel rods or wire mesh as reinforcement material. For driveways and garages, the area inside the boundaries of form is then filled with dirt and then the installation of the gravel is the essential part. At the top concrete is poured to add firmness to the base.
To smooth put the concrete pour, a screed board is required. The screed board removes the excess pour with side to side motion, but this work is hard and demands to be done by hand. For floating, the surface bull, magnesium, or wooden float is required depending on the project.
Small projects use magnesium and wooden float while larger projects require bull float. The purpose of the float is to fill any remaining voids leveling out the surface.
For finishing a margin or pointing trowel, Edgar, control joints, jointer, a cuff saw, and power trowel is required. Margin trowel is used to separate concrete from the form. Edger rounds off the edges of the form to avoid chipping off. Control joints and jointers are used for large slabs of concrete in driveways or garages to prevent them from cracking. These jointers are run along the concrete to create a straight line. A cut saw is used to remove the jointers once the concrete cures. The power trowel is required for large concrete jobe to smooth them out. expansion joints are also placed to avoid cracking due to expansion and contraction effect of nature.
Curing requires a lot of water but in small amounts. The concrete is covered with a plastic sheet and requires to be kept damp regularly for five to seven days after pouring.
