USING BASALT REBAR IN CONSTRUCTION: A GUIDE

  Basalt rebar is a type of concrete reinforcement that is made from continuous basalt fiber, a product of melting basalt rock without any additives. It offers a number of advantages over steel or fiberglass rebar in terms of strength, weight, durability, and environmental impact.   Strength : Basalt rebar has a tensile strength of 1400 MPa, which is 2.5 times higher than steel and 8 times higher than fiberglass. This means that it can withstand higher loads and stresses without breaking or deforming. It also has a similar thermal expansion coefficient as concrete, which prevents cracking due to temperature changes. Weight : Basalt rebar is 5 times lighter than steel and 3 times lighter than fiberglass. This reduces the weight of the concrete structure and transportation costs. It also allows for more flexible and creative designs with smaller diameters and wider spacing. Durability : Basalt rebar is resistant to corrosion, rust, alkali, acid, and salt water. It does not need ...
