· There are many types of building materials used in construction such as Concrete, Steel, Wood and Masonry. Each material has different properties such as weight, strength, durability and cost which makes it suitable for certain types of appliions. The choice of materials for construction is based on cost and effectiveness to resisting the ...
In the late stages of hardening the bond strength of concrete components is determined by the adhesion of the filler to the binder stone. At this the finelydispersed mass of polymineral technogenic filler creates not only the concrete frame, but acts as the binding component at the artificial composite structure formation.

Introduction to lightweight concrete: Light concrete is made of lightweight aggregate, it is also called concrete. Since this cement consists of lightweight aggregates, it is used in coarse aggregates and sand, clay, y slag, clinker, and crushed stone, aggregates of organic and inorganic.. This concrete saves 15 to 20 % in the cost of construction of floors and roofs.
· Multidisciplinary studies of metallurgical slags are mostly focused on: (1) reuse of these materials (for construction purposes or element recovery), (2) potential environmental impact of these wastes, (3) exploration how metallurgy evolved through human history.
· Rockfill dams are one of two types of embankment dams, the other being earthen dams. These structures are effective because the force of the river or reservoir hits the impervious zone and is transferred to the firmly packed transition zone where water can slowly begin to filter through the dam. When clay is used for the impervious zone, this ...
Hollow concrete blocks are one of the useful construction material, these are lightweight blocks and used for loadbearing on nonload bearing walls. In general practice, hollow concrete blocks are 30 cm X 20 cm X 15 cm ( 12inch x 8inch x 6 inch ) in size. In general practice, for hollow concrete blocks, the face thickness must be at least 5 cm ...

For production of cellular concrete, Portland cement, "burnt lime", and finepulverized blast furnace slags, with a hardening activator are used as binders. As silica components, quartz sand or "fly ash" obtained by combustion of pulverized fuel in power plants as well as secondary products of different ore dressing treatments are used.

· The cores also have a benefit in sustainability terms in reducing the volume of concrete used. Units are generally available in standard 1200 mm widths and in depths from 110mm to 400 mm. There is total freedom in the length of units. These type of slabs are Pre cast and it is used where the construction has to be done fast.

Concrete is a unique material, which is why we take the challenge of sustainability seriously as a sector. Our GNR reports show that cement companies have already achieved a significant % reduction in CO 2 per tonne of cementitious product since 1990 (among other facts).; Harnessing and leveraging innovative technologies will be key to unlocking the sector's sustainable future.
· Aircooled slag is hard and has fine properties, so it is suitable as an aggregate. Adding granular slag to concrete increases its strength and durability since the slag has good cement properties. Granulated and expanded slag is practiced as a light filler in construction due to its low density [ 30, 31 ].
