Reinforced Concrete Beams Without Shear Reinforcement Using Fiber Reinforced Concrete and Alkali-Activated Material

Abstract

Concrete, which is based on the use of Portland cement as a binder, often becomes a construction material in the construction industry. Concrete itself, however, exists in a number of modifications that are intended for specific applications. Especially with regard to the development of materials engineering, variants were created, which include, for example, fiber reinforced concrete with improved tensile properties and alkaline-activated composite, which produces less CO2 emissions. The aim of the presented article is to verify the concept of using a combination of reinforced concrete and alkaline-activated material in the application of reinforced concrete beams without shear reinforcement. Components of the experimental program are static load tests, which are evaluated in detail with regard to the formation and propagation of cracks. Laboratory tests are also part of the experimental program, which focus on a detailed description of the properties and the possibility of a technological solution.
