Easy and safe usage: Just mix Crackmax chemical powder with 30% water, pour into holes, and then it expands to crack. It is environmental friendly. It releases no toxic or harmful substances of any kind. CrackMax Expansive Mortar can be used safely, while providing controlled expansive cracking.

What is the composition of mortar?

Conventional mortar is a mixture of cement, lime, and sand, with the proportion of cementitious materials to sand typically near 1:3. In some localities, a proprietary product called “masonry cement” is used to replace the Portland cement and lime in the traditional mix.

What is expansive agent?

Introduction. Expansive agents are admixtures sold as powders that are added to concrete. In the early stage of hardening, they produce a controlled internal reaction so that the apparent volume of concrete increases. A concrete containing an expansive agent is also known as shrinkage compensated concrete (ACI, 2011).

How do you break a rock without explosives?

Expanding Grout is a non-explosive demolition agent used for breaking rock and concrete. Also known as Expansive Demolition Grout, it is designed to provide job sites with non-explosive solutions for the demolition of rock and concrete in environmentally sensitive areas.

What is the ratio for mortar?

For a standard mortar mix this normally on a ratio basis (usually around 3 or 4 parts building sand to 1 part cement) recommendations vary – but you don’t want the mixture to be too wet or too dry.

Which chemical composition has highest content?

1. Which chemical compostion has highest content in OPC? Explanation: Lime forms nearly two-third (2/3) of the cement. Therefore sufficient quantity of the lime must be in the raw materials for the manufacturing of cement.

What is flux in cement?

A flux composition for cement comprises mainly wollastonite. One of the compositions of the flux is wollastonite 99%, fluorite 5-15% and gypsum 30-35%. The flux is added during the preparation of the cement raw materials and comprises 1-10% of the admixture.

What are the advantages of choosing expansive mortar?

Since expansive mortar can be easily formed into ‘sausages’ and inserted into holes, it’s perfect for hard to reach areas of horizontal rock too. Today, more companies around the world are choosing expansive mortar as a smart alternative to explosives or gas blasting.

What is the raw material for expansive cement?

The raw material in this type of cement contains, portland cement, anhydrous tetracalcium trialuminate sulfate (C 4 A 3 S), calcium sulfate (CaSO 4 ), and lime (CaO), which are grounded and expansive cement is formed. 2. M Type expansive cement The Portland cement clinkers are grounded with calcium sulfate. 3. S Type expansive cement

Can you use expansive mortar for stone cracking?
