A pozzolana is a natural or artificial material containing silica in a reactive form. By themselves, pozzolanas have little or no cementitious value. However, in a finely divided form and in the presence of moisture they will chemically react with alkalis to form cementing compounds.
Fly ash has little cementing property when only water is added, its reactivity could be activated by OH [2,3], in…
Concrete slabs are one of the most common structural elements of modern buildings and infrastructures including residential, commercial plazas, hospitals or buildings having industrial significance. Typically 4 to 20 inches of reinforced concrete mat like element is…
If in 2018 you are not familiar with this highly durable and beneficial construction material than you must read each an every word of this article about Polymer Concrete. Because I\’ll be going through all the aspects of Polymer Concrete including its definition, how…
The word plum means large stones which are termed as boulders or coarse aggregates if technically speaking.
The plum concrete is actually an economical variation of mass concrete. It is one of the many different types of concrete. The use of plum concrete is preferred if the required thickness of PCC is excessive or large.
This is mainly done below the foundations where due to steep slope of the…
The Stamped concrete can be defined as a finish that is provided to the concrete in its wet state. Specific designs or patterns are stamped on the concrete in its plastic state as shown in the figure-1 below.

What is Ultra High Performance Steel Fiber Reinforced Concrete (UHPFRC)?
July 13, 2017
Ultra-high performance Fiber Reinforced Concrete is a relatively new construction material having minimum coarse aggregate (usually size greater than 6-7 mm is not used) having discrete random steel fibers uniformly distributed across the concrete matrix with the basic…
You might have seen and used hollow blocks for building walls which are very effective as an insulation and light weight partition option. Similarly there is a concept recently introduced as hollow slab or hollow core slabs.
Hollow Core Slabs are actually precast, prestressed concrete slab panels having circular openings throughout the length of the panel. Hollow core slabs are sometimes also…
Materials added to concrete during or before mixing are referred to as admixtures. They are used to improve the performance of concrete in certain situations as well as to lower its cost. There is a rather well-known saying regarding admixtures, to the effect…
Concrete is one of the widest used construction material whether it is a dam or a house or a bridge or flyover. Concrete is basically of three components water, aggregate and cement. Aggregate acts as a filling agent while cement mostly Portland cement act as a binding…
