The solution to the problem of stones in mortar is recommended by the manufacturer of dry powder mortar equipment

The stone problem refers to a large number of stones in the mortar, which seriously affects the service performance of the mortar, so how to solve it? Dry powder mortar equipment manufacturer to let you know

Strictly clean the sand in the machine

Strengthen the working awareness of forklift drivers to avoid mixing stones when shoveling sand

Try to avoid too close distance between different material buckets, and ensure that the sand bucket wall is not perforated to ensure that materials will not be mixed

The sand silo and belt shall be strictly cleaned

The manufacturer of dry powder mortar equipment suggests to regularly check the screen of sand screening machine to avoid sand quality fluctuation after damage

Viscosity is also a parameter to reflect whether the mortar is easy to use. The mortar with normal viscosity is smooth in construction and is not easy to fall off on the wall. When the viscosity is not good, the mortar looks scattered, which is difficult to construct. When the viscosity is too good, the mortar is not easy to dry on the wall, and the worker sticks the scraping ruler when rubbing and pressing, which will also be difficult to construct.

The viscosity of mortar will increase in winter, and the amount of viscosity adjustment admixture should be reduced accordingly.

When the temperature is high in summer, the viscosity of mortar will decrease and the amount of admixture will increase accordingly.

Generally, the dosage of admixture shall be increased or decreased by about 1kg / m3 for every 5 degrees increase or decrease in temperature

Stone powder also has a great impact on mortar viscosity. Too many impurities in stone powder will show too low whiteness. When used in mortar, there will be poor mortar viscosity and mortar bleeding

It is better to control the whiteness of stone powder above 40 degrees. Too low whiteness means that there are too many impurities, which has a great impact on the quality of mortar.

Solution to dry and hard mortar:

We should also consider the change of climate and environment and appropriately adjust the dosage of regulator. To achieve the same opening time, the higher the temperature, the greater the amount of regulator.

In principle, the opening time of masonry mortar shall be adjusted to be 3 ~ 4 hours longer than that of workers, and the opening time of plastering mortar shall be 1 ~ 2 hours longer than that of workers. The opening time of ground mortar shall be determined according to the actual construction operation on the site (the shorter the opening time is, the better on the premise of meeting the use requirements)
