PPT-Strength of Concrete

Strength is the most valuable property in the concrete because it is directly related to the structure of cement paste The most important factor in the strength of concrete is watercement ratio The other mix proportions are of secondary importance. If cement is used as cementing material in the mix, it is known as plain cement concrete.. If steel rods/bars are embedded in the plain cement concrete, then it is called reinforced cement concrete abbreviated as R.C.C. Concrete. The word “concrete” originates from the Latin verb “concretus”, which means to grow together.. Concrete As A Material . Concrete, literally, forms the basis our modern life:. Roadways/transportation systems. Presented by Mariah Safritt. July 30, 2015. Motivation. Repairing infrastructure is expensive and uses a lot of resources, not efficient or sustainable. UHPC is stronger, so less can be used while obtaining higher strengths. Chapter 2. Chapter Topics. Portland cements. Supplementary cementitious materials. Blended cements. Aggregates.

BUILDING TECHNOLOGY AND MANAGEMENT. NEED. PCC has low tensile strength, limited ductility and little resistance to cracking. PCC develops micro-cracks, even before loading. Addition of small, closely spaced and uniformly distributed fibres act as crack arresters.. 2. What is Concrete?.
