Cement-sand mortar for bricklaying

usual brick masonry mortar cement-sand type is produced by mixing two main components: sand and cement.Proportions solution for bricklaying are typically 1: 4 ratio or 1: 6.The objective of any solution that does not prevent bias in laying bricks to each other.Therefore, the solution for laying bricks in building construction is experiencing a compressive load and displacement.That is why this type of solution skinny.In some cases, such solutions can be added to the clay or lime, these optional components allow the solution to give plasticity and flowability.In rare cases, it can be used instead of lime washing powder or soap.But laying brick, such a mixture will flow into all the available slots in the brick, which will negatively affect its insulating properties.

Solution is prepared by laying bricks in a simple manner: mixing the core components (cement: sand) in dry form and in a subsequent mixing before use with water.It should be formulated once a small amount of the solution (the recommended amount of 25-30 liters).But if the process is conducted in laying bricks few hands or implied use of a large amount of fast then you can immediately perform a large number of the batch solution and, if necessary, should be used and a cement mixer.

solution for brickwork as mentioned above, is designed to fill the space between the individual bricks, stones or blocks of building materials.And so the quality of the solution has a direct impact on the solidity and strength of the whole structure and therefore the longevity of its operation.

Solution for bricklaying is composed of two types of components is fillers and binders.Depending on the binder component solutions are distinguished air curing, water curing, as well as hydraulic.Usually in the masonry used the first type of solutions.Depending on the amount of binders in solution they are divided into simple and complex.The masonry is used usually simple solutions.In this case, the binder is either cement or lime.The complex solutions of binders can be used simultaneously, for example, cement-lime, lime, cement, clay, etc.Such complex solutions are used for specific masonry where necessary that the solution has a high ductility properties.

solution for masonry still divided on the strength.The indicator mark is determined or in other words the ability to withstand the solution in compression.For solutions used in masonry, the following marks: 0;2;4;10;25;50;75 and 100. For more specific needs - the construction of hydraulic structures and special constructions can be applied solutions marks 150 and 200. This brand is characterized by signs of freshly svezheottayavshego or solution that is not scored yet sufficient elasticity and strength of the setting and hardening.To check mark is produced a solution from a cube with edge 7 cm. And after 28-denvnogo term curing thereto a force is applied in compression.The temperature of the laboratory may vary from 15 to 25 degrees Celsius to plus.Moreover it produced three sample solution and fences made at the beginning of kneading, middle and end of the kneading.

Besides the strength characteristics of mortar for bricklaying must have water retention and mobile settings.These parameters allow the solution uniformly fill all of the space on the seams, which in turn leads to improved coupling characteristics of the solutions and the surfaces of bricks (stones).
