Determining Rebar Size for a Concrete Slab

Aug 11, 2009The size of rebar you need for a concrete slab is determined by local and state building codes.Rebar is the reinforced metal bar that is placed in a concrete slab for extra stability and strength. Building Codes and Rebar Size. Building codes will help you determine the length and size of rebar you need to use for the concrete slab you are pouring.

Critical Particle Size Distribution for Cement using Laser

Generally speaking the larger the distribution percentage of particles between 3-30μm, the better the quality of the cement 2. Experience tell us that the optimal size distribution is when 60-70% of particles in the overall distribution are within the range of 3-30μm and 10-20% are smaller than 3μm2. In the grinding process, overgrinding

Citrus Trees and Root Size Around Cement

This is a response to a lack of water and nutrients that are being pulled up by the roots to support the leaves. In citrus trees there are more shoots than roots, with an average ratio of 1 to 4 or 1 to 2 roots to shoots. This ratio will be even higher when the plant is compressed by thick cement and roots are prevented from growing.

What Size Pressure Washer Do I Need To Clean Concrete?

Pressure wash by holding down the sprayer. For really tough stains you can hold the sprayer about 4 inches from the concrete but for standard cleaning 6 to 8 inches from the surface will suffice. Make sure to spray in overlapping strokes to ensure an even coverage.
