The proportions and the brand of cement mortar for masonry , plaster and construction

Before we consider the proportions of cement mortar, it is necessary all the same to clarify the question of the solution.For any individual construction people use cement solutions, using the cement and sand.However, unlike the professionals, many people simply do not realize that mortar and concrete solution - a few different things, and therefore used differently.

difference cement and concrete solution

fundamental difference between these solutions consists in the fact that if a slurry, except for the cement, sand only applied to the concrete mix - also gravel (or gravel).The conversation will go just about cement slurries.Therefore, in the first approximation, we can say that the concrete mix - this is "fine" cement.For each "type" of work preparing its membership.This is because the purpose for which it will be applied.

every "structure" is operated (or will be used) under certain conditions.Therefore, the conversation should be conducted is still not on the brand of cement, which is "shuffled", and it is about the brand of cement mortar, which should in turn result.Make a solution is a measure of hardness, strength and durability of finished "structure."It is necessary to take into account parameters such as climatic conditions, changes in temperature, humidity, pressure.It is also important, whether this place packing solution testing subsequently any load.

Any mortar consists of two components - cement and sand - "involved" in the water.Food Technology all such solutions the same.In preparing first a dry mixture consisting of course, sand and cement.The difference between the brands of cement mortars is that each of them takes a certain brand of binder (cement).The second difference - in the proportions in which the components are taken.In other words, what is the ratio between the mass of cement and sand mass.

Forms solutions

solutions are divided into fat, thin and normal.Fatty differ from the norm a lot of cement.Their drawback - rapid cracking.The lean solution excess sand, it is difficult to work with, and its strength is low.During construction works, as a rule, used mortars grades 15, 50, 75, 100 and 150.

Appointment solutions and the proportions of different brands of cement

cement solutions are plaster, masonry and construction.They are distinguished by the quality of sand used and the ratio of the mass of sand - cement.For plastering of walls, for example, use a fine-grained sand.

practice for private construction, a solution is: 1 part cement to 2 - 3 sand.This cement should use 300 or 400. If the sand is more, in the future perhaps premature failure of masonry.

solution Brand 100

If the sand is taken small, it is suitable for plastering and masonry works.If the cement brand "400", then 3.5 parts of sand.If "300" cement - 2.5 parts.It can be used instead of sand granite dust.The ratio of 1: 3 cement "400".

Brand solution 150

also suitable for masonry and plaster.If you want to make a floor screed, the sand should be coarse.

should be borne in mind that very often use different fillers.Adding gypsum solution, hydraulic lime, clay improves its elasticity.
