When it comes to picking the right rapid hardening cement for your project, you need to consider important factors such as:

– What type of project are you doing?

– How much does the rapid hardening cement cost?

– What is the cure time for the rapid hardening cement?

– How fast does rapid hardening cement set?

– Is the rapid hardening cement for indoor or outdoor applications?

– Will you be able to find rapid hardening cement in your local area?

Read below for all of these answers and more.

Rapid hardening cement is a special blended cement that accelerates the setting time of concrete. It is used in cold weather construction to speed up the initial set of a concrete mix. Depending on the brand and formulation, it can accelerate the setting time as much as 30 minutes after mixing or more.

When to use rapid hardening cement

There are several situations when rapid hardening cement may be used in place of regular portland cement:

* bond beams, steps, footings and other forms which require fast removal in cold weather applications

* thin sections such as curb and gutter or pavement slabs – where rapid strength gain is necessary for traffic control

* foundations and other structural elements where early set is desired for stripping forms, etc.

Rapid hardening cement is a hydraulic cement that sets, hardens, and gains strength quickly. It is used for concrete construction where a fast initial set time is required. Rapid hardening cement may also be used as a final finishing coat in the repair of concrete surfaces or as a concrete surface hardener.

Rapid hardening Portland cement can be distinguished from ordinary Portland cement by its physical properties. The rapid hardening Portland cement has higher fineness, specific surface, and compressive strength than ordinary Portland cement.

There are two main differences between rapid hardening Portland cement and ordinary Portland cement: 1) An increase in structure, caused by an increase in ratio of C3S to C2S; 2) A decrease in amount of water needed to hydrate the C3A.

We recommend that you do not use rapid setting concrete on bridges or buildings because it does not have the same durability as standard concrete. If your project requires a fast cure time we recommend using our fast setting mix design instead.

When it comes to concrete mixes, rapid hardening is a type of cement that can be incredibly useful but it’s also one that people have a lot of questions about. This article is going to tell you everything you need to know about rapid hardening cement, including what it is and how it works, so that the next time you’re ordering concrete mix, you’ll know just what to ask for.

First thing’s first — what exactly is rapid hardening cement? It’s a form of portland cement that uses calcium aluminate in place of calcium sulfate as its setting agent.

Rapid Hardening Cements are the cementitious materials that are used to increase the rate of hardening and strength development at early age. It is a modification of ordinary portland cement. When rapid hardening cement is mixed with water, there will be an increased rate of hydration and higher exothermic heat evolution. Rapid Hardening Cements are used in all concreting works where sufficient strength is required at an early stage.

It is 2 to 5 times stronger than normal portland cement. However, moderate temperature should be maintained during manufacturing, storing and transportations or else it will react with moisture in the air and form lumps which are not suitable for use. Rapid Hardening Cement has a specific gravity of 3.15 and initial setting time of about 30 minutes.

Rapid Hardening cement can be used for precast concrete products such as pipes, paving blocks, tiles, sleepers etc. High strength developing capacity makes it suitable for mass concreting works such as dams, bridges, heavy foundations etc where quick removal of shuttering/formwork is necessary.

Portland cement is the commonest hydraulic cement. It’s produced by mixing clinkers of calcium silicate, aluminate, and ferrite with calcium sulfate in finely ground form. The ratio of the clinkers to gypsum is usually 3:1 or 4:1 by weight. The mixture is then heated to a temperature of 2,700º F and ground into a very fine powder to produce ordinary Portland cement.

Rapid hardening cement is a special type of Portland cement that produces concrete that sets and gains strength faster than normal Portland cement. Rapid hardening cement also requires less heat for hydration as compared to ordinary Portland cement and has a lower ultimate strength than ordinary Portland cement at all ages. Rapid hardening cement is used when rapid strength gain is required, such as on roads and precast concrete products.

As a concrete professional, when you are hired for a project, you need to know exactly what type of concrete to use. This can be a challenge due to the fact that there are many different types of concrete available on the market today.

Each is made for different purposes, and depending on the objective of your project, the wrong choice of concrete can lead to failure. The right choice will allow you to finish your job on time and within budget.
