1/6/2021 · ACI Concrete Terminology. Creep is indicated when strain in a solid increases with time while the stress producing the strain is kept constant. In more practical terms, creep is the increased strain or deformation of a structural element under a constant load. Depending on the construction material, structural design, and service conditions
GlassFib re Reinforced Concrete (GRC also known as GFRC) is a type of fib re reinforced concrete. GRC are mainly used in exterior building façade panels and as architectural precast concrete. This material is very good in making shapes on the front of any building

Concrete BlockBackgroundA concrete block is primarily used as a building material in the construction of walls. It is sometimes called a concrete masonry unit (CMU). A concrete block is one of several precast concrete products used in construction. The term
Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures. Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during the production of concrete, etc
1. Central-mixed concrete is mixed completely in a sta-tionary mixer (Fig. 10-3) and is delivered either in a truck agitator (Fig. 10-4 bottom), a truck mixer oper-ating at agitating speed (Fig. 10-3), or a nonagitating truck (Fig. 10-4 top). Fig. 10-5 illustrates a central mix
