The recommendations of fiberglass used in the reinforced concrete

Production of glass fiber reinforced concrete is not just to add fiberglass chopped strand mat some fiber to the concrete mixed. There are many important considerations to keep in mind. Here are a few:

1. The fiber content - glass fiber reinforced concrete relies on fiberglass high load. If there is not enough fiber in concrete, it will not be in the face of high tensile load, and it will not be resistance to cracking and breakage. Fiber content changes, but at least 3% of the total weight of the mixture. Some mixed, up to 10% of the fiber content. The more fiber, glass fiber reinforced concrete exhibits stronger, but does increase the fiber will lead to lower operability, and even endanger the compaction. However, the fiber strength is lowered due to the worse the problem. Some concrete countertops teacher suggested that only 2% of the fiber. I do not know the motivation behind this is, but 2% is not enough. 3% minimum.

2. Hybrid fiber - orientation is also very important. Truly random fiber orientation means more fibers are needed, because many fibers will point in the wrong direction. Some concrete countertops teacher support and recommendations to create a fluid mixture into the form. This was not done, because it leads to random fiber orientation.

3. The method of reinforcement used. Usually there are concrete and glass fiber reinforced concrete using three different levels of reinforcement. Each type has different benefits.
