Rapid Set Cement Portland Cement

Rapid Set® cement is rapid-hardening calcium sulfoaluminate (CSA) cement, not a portland cement. The selection and proportioning of the raw materials, many refinements during the manufacturing process and comprehensive quality control of CSA Cement yields high-quality, durable long-lasting applications.

Shrinkage causes concrete to crack and since Rapid Set cement concrete is low shrink, there is virtually no cracking. It is more resistant to sulfate and other types of chemical attack. Rapid Set cement helps projects to be stronger and more durable.

Your finished projects are better looking and last more than twice the lifetime of portland cement concrete.

Conventional cement, also known as Portland cement, is the most common cement used in concrete. Portland cement is made by combining a mix of raw materials, usually limestone, clay and shale, at very high temperatures. Although portland cement has been used successfully for many years, it has its limitations.

Portland cement concrete tends to shrink and crack excessively. It is susceptible to attack by prevalent chemicals such as sulfates. It also reacts destructively with certain aggregates due to the alkali-silica reaction (ASR). These limitations cause the concrete to become unsightly, less durable, increasing the possibility for structural problems.

You will need to re-repair and replace your concrete more often.

Strength & Time

Rapid Set cement concrete achieves structural and drive on strength in one hour, and final strength in one day. When using Rapid Set cement products, you will complete your projects faster and have more time to enjoy the important things in life.

Portland cement concrete takes approximately 24 hours to achieve structural or drive on strength and one month to reach final strength. When using portland cement, you will need more working time to complete your projects.
