clouds cold freezing frost

Cold Weather Concreting As per ACI 306-R10, Cold Weather Concreting is defined as a concreting process – mixing, pouring and curing, below atmospheric temperature of 4o Celsius (40 o F) over the recommended protection period as per the specifications. Protection period is defined as the time required for the concrete to develop early strength of … Read more

All about Concrete Admixtures | Dosage & Cost | Admixture Market in India


Concrete Admixtures Concrete Admixtures are those ingredients or additives (other than aggregates, cement, water) added to the concrete during the time of mixing to enhance or alter its mechanical and material properties. The desired characteristics such as high workability, high compressive strength, setting time, and durability parameters can be altered by the addition of admixtures. … Read more

Construction Waste Management | Construction & Demolition Waste | Classification

Demolition of building generating construction waste (Source :

Construction & Demolition Waste The growth in the construction industry triggers waste production to exponential levels. The waste generated from the construction industry is commonly called as Construction & Demolition Waste or C&D waste. Most of the waste materials in construction industries are non-biodegradable and inert materials. Construction waste materials are heavy, dense, bulky in … Read more

Groundwater Mapping | Aquifer Mapping | Significance & Procedures


Groundwater Mapping or Aquifer Mapping Groundwater mapping or aquifer mapping is the process of delineating the presence of ground water in aquifers, followed by the analysis of its quality, quantity, movement and sustainability. About 30% of world’s fresh water supply is ground water, i.e., 0.76% of entire world’s water. Researches confirm that it is a … Read more

Effects of Capillary Water on Structures and Foundation | Preventing damage


What is meant by Capillary water in buildings? Construction materials, like concrete, aggregates and sand, are porous and allows water molecules to rise due to capillary action. This creates a ring of dampness in base of buildings or structure including lateral walls due to accumulation of capillary water. The principle behind the capillary rise is … Read more

Marine Corrosion of handrail baseplate and anchor bolts on Jetty or Pier 3.jpg -

Why Inspection & Structural Maintenance is important? “ Life expectancy “ is not just a term associated with a living, breathing being, but even with an immobile non-living element, like a building. According to researchers, the general lifespan of a concrete building lies in the average range of 75 to 100 years. And for a … Read more

Construction on Permafrost | Design Considerations & Maintenance

Construction on Permafrost

Permafrost in Construction Permafrost is the soil or rock with or without water that continuously remains at a state of 00 C (320F) or below for two years or more. It is mostly found in subzero Polar Regions and high-altitude mountain ranges. Building construction on permafrost is quite different from normal construction methods that we … Read more

Cracks in Concrete | Types & Causes of Concrete Cracking

Flexural cracks on pavement slab due to lack of reinforcement or expansion of subgrage -

Cracks in concrete are quite common phenomena. But unforeseen cracking in concrete that are not anticipated in design stage, affects the durability and integrity of structure. This in-turn results in poor performance on the structure over its service life.

Reinforced Cement Concrete (RCC) | Simple Explanation | Significance

Reinforced Cement Concrete (RCC) Definition of Reinforced Cement Concrete    Reinforced Cement Concrete (RCC) is a composite building material consisting of structural concrete reinforced with a reinforcing material like steel. The most common reinforcement used is steel, due to its complimentary properties and it is called steel reinforced cement concrete or simply Reinforced Cement Concrete. … Read more
