Self-healing Concrete | How Self Healing Concrete Works

by
Self-healing Concrete

What is Self-healing Concrete? Self-healing Concrete is defined as a type of concrete that exhibits self-healing properties. Self-healing or self-repairing of concrete is that property by which concrete undergoes crack repair and rectification, either by autonomous or by autogenous methods. The characteristics of concrete that defines all of these activities is it’s durability. Durability is … Read more Self-healing Concrete | How Self Healing Concrete Works

Demolition of building generating construction waste (Source : youtube.com/diecastmania)

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 Construction Waste Management | Construction & Demolition Waste | Classification

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 Effects of Capillary Water on Structures and Foundation | Preventing damage

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 Maintenance of Residential Buildings | Types | Objectives | Checklist

Lateral Torsional Buckling | Factors influencing LTB

by
lateral torsional buckling

Lateral Torsional Buckling occurs in unrestrained beams. A beam is unrestrained when its compression flange is free to displace laterally and rotate. When I sections are used as beams or beam columns the compression flange is under compressive stress and has a tendency to buckle but it is attached to the tension flange which resists … Read more Lateral Torsional Buckling | Factors influencing LTB

Preloaded Bolts (Pre-tensioned Bolts) | Advantages | Applications

by
Manual Pretensioning of Preloaded Bolts

Preloaded Bolt Bolts are tightened such that a high tension, usually above yield strength, is developed in the bolts, these are called preloaded bolts. The plates of the connection are thus clamped together and shear transfer between the plates is achieved through friction. Preload is the tension load developed in a fastener while tightening. The … Read more Preloaded Bolts (Pre-tensioned Bolts) | Advantages | Applications

6 Crucial Design & Construction Requirements of Formwork (Shuttering)

by

Formwork The function of formwork (Shuttering) is to hold freshly placed and compacted concrete till it has gained sufficient strength to be self-supporting. It also serves the purpose to produce a concrete member of the required shape, size and the desired finish. 6 Major Design and Construction requirements of Formwork The formwork should be sufficiently … Read more 6 Crucial Design & Construction Requirements of Formwork (Shuttering)
