You then want to move up and down the concrete in straight lines. Just don't point the sand spray at the concrete and leave it in one place, or it may damage the concrete. 2. Using a Pressure Washer. Another effective method for removing paint from concrete, especially if you are outdoors or in a garage, is by using a pressure washer.

Concrete with enhanced or high abrasion resistance should demonstrate a target compressive strength of approximately 50 MPa. The surface can be considerably enhanced against grinding abrasion through the use of micro silica and/or surface hardener scattered on the surface. In order to boost resistance against percussive or striking impact, the ...

Non-hydraulic cement doesn't set in wet conditions or underwater. Instead, it sets because it dries and reacts with Carbon dioxide in the air. It is resistant to attack by chemicals once set. Hydraulic cement (e.g., Portland cement) sets and becomes adhesive because of a reaction between the dry ingredients and water. The reaction ends up in ...

Concrete is an inherently resilient and durable construction material, but it isn't immune to the wear and tear of everyday use. Such wear and tear have implications beyond just the integrity of a building or structure — it can pose safety hazards and added costs. Concrete erosion — the deterioration or wearing away of concrete […]

In the manufacture of concrete units the three important materials used are cement, aggregates and water. Constant care in the proper selection and gradation of the aggregate, assurance that the cement meets or exceeds standard specifications and a supply of clean, pure mixing water are absolutely essential to the economical production of units of uniformly high quality.

Cement and Concrete. Concrete is a rocklike material produced by mixing coarse and fine aggregates (Portland cement, and water) and allowing the mixture to harden. Portland cement may also be manufactured from any number of raw materials, provided that they are combined to yield the necessary amount of lime, iron, silica, and alumina.
