Urban construction requires high-strenth concrete and reinforcement solution for demanding projects like highrise buildings or infrastructure projects where the concrete has to withstand high pressures. In recent years, Sika has expanded its presence in the fast-growing concrete reinforcing fiber market, with several acquisitions and investments in new production lines.
Just five percent of installed concrete contains fibers. Experts anticipate that concrete reinforcing fibers will usher in the same magnitude of progress in construction as admixtures have since their introduction to the market.
Studies have shown that adding fibers to concrete increases flexural strength 2.5-fold. Fibers also provide improved corrosion protection, fire resistance, and extend service life.
Because of its greater efficiency, fiber reinforced concrete is set to grow at an estimated average of 7.2 percent a year in the period between 2015 and 2020. The advantages of using fibers include a reduced site workload because less rebar needs to be used.
