Cement dries in stages that take about 30 days to complete. It takes one to two days for cement to dry enough for people to walk on and five to seven days before people can drive on it.Know More
The weather has a large effect on how quickly cement completes the curing process. Factors such as rainfall, sunlight, wind and humidity are all contributors. Treatment of newly poured cement depends greatly on the weather conditions as moisture imbalances can cause cracking as the cement dries. Concrete will cure harder and stronger if it is allowed to dry slowly. If conditions are moderate, covering the cement with plastic protects it. If temperatures are 80 degrees or above, frequently watering it down with a garden hose keeps it moist and prevents cracking. In the right conditions, concrete will reach about 90 percent of the curing process within a week.
There are accelerator products on the market that help to speed up the drying process. Accelerators are chemicals added to a concrete mix that reduce the set time by increasing the rate of hydration. There is also Portland cement, which sets and hardens due to a chemical interaction with water. The curing process is the most important step in achieving strong and even cement.Learn more about Building Materials
The basic mix ratio for concrete is one part water, two parts cement and three parts sand. An alternative ratio is one part cement, two parts sand and three parts gravel with enough water added until the mixtures reaches the consistency of thick mud. Lime is also a common additive to the mix.Full Answer >
Concrete is a mixture of cement, water and aggregates, such as sand, coarse gravel or crushed rock. After it hardens, concrete is resilient, durable, resistant to environmental extremes and capable of supporting heavy loads. Grout is similar to concrete in its ingredients, but with a fine aggregate grade and a higher water content that allows it to flow easily and be used as a filler or joint sealer.Full Answer >
To install shower tile, begin by putting a cement backer board in place. Dry lay the tile on the floor or on a board to preview its look on the shower walls. Space out the layout, put the tiles in place, and add grout after the mortar has dried.Full Answer >
In general construction use, there are 11 different types of cement, such as quick-setting, rapid-hardening and low-heat cement. Each type of cement is composed of different materials, and has markedly different uses, ranging from concrete that is aesthetically pleasing as flooring to concrete that can withstand high levels of acidity.Full Answer >
