Q:

What is a blinding concrete plate in construction?

A:

A blinding concrete plate is a base layer that is cast into a footing trench before installing any reinforcement for foundations. It has a minimum thickness of about 2 inches.

Blinding concrete plates are laid to level the surface of a footing trench. These concrete plates also serve as under layers for ceramic tiling and flooring purposes. Compared with structural concrete, blinding concrete can withstand much lower pressure and is therefore used for lighter duty construction.

Blinding is used to create a strong level surface for either of the two purposes: an underlying mass fill and a concrete slab. Steel mats are used as reinforcements either on the entire blinding concrete layer or only on those areas that have highest static loads.

    How do you raise the pH level of a swimming pool?

    A:

    The pH of a swimming pool is raised by adding a pH increaser, which contains soda ash (sodium carbonate) as the active ingredient, and by testing and monitoring the alkalinity of the pool. The ideal pH level in a pool is between 7.0 to 7.6, which basically is near the same pH level as the fluid the lubricates the eyes. Low pool pH may cause several problems such as corrosion of the metal parts, erosion of the tile grout or plaster, skin and scalp irritation and a burning sensation in the eyes and nose.
