A dead load of light concrete is much less than that of ordinary concrete. Light Weight Concrete can be created by adding lightweight aggregates. Light Weight Concrete can also be created by entering the air in normal concrete.
HAVE A LOOK HOW YOU CAN APPLY THE LIGHT WEIGHT CONCRETE (LWC) IN YOUR CONSTRUCTION PROJECT! Monolithic ed concrete is made directly on the site. Density from 100 to 1200kg/m 3. Production technology includes the supply of eding agents, which attach porosity to the material. We supply the mortar to the …
This blog illustrates the benefits of using structural lightweight concrete made with expanded shale, clay and slate, educating engineers, architects, specifiers and …
Cellular lightweight concrete has several advantages associated with their applications: Termite proof and resistant towards freezing issues. 1. Lightweight: Cellular lightweight concrete is low on weight and thus it …
The Concrete Calculator estimates the volume and weight of concrete necessary to cover a given area. Purchasing slightly more concrete than the estimated result can reduce the probability of having insufficient concrete.
Lightweight concrete mix. They can decrease dead load up to 20% – 80% depending on their types and components used within them with alteration in strength. Moreover, even they have low structural strength; their strength is still higher than the masonry elements like a brick. The air is an excellent insulating agent.

Advanced Concrete Technologies is the application and distribution subsidiary of Costarchem Nigeria Ltd with a track record of over 15 years, our collective experience and expertise, and expertise are unmatched in concrete solutions, construction chemicals, and waterproofing technologies in Nigeria.
Light-weight Concrete (LWC) or Light-weight Aggregate Concrete (LWAC) has been adopted by the construction industry for many years. Compared to the regular reinforced concrete, LWC has a lower density while maintaining the concrete strength level. This is mainly contributed by the lightweight aggregate used in the concrete.
The less weight of light weight concrete is due to the usage of fine and course lightweight aggregate. When the complete aggregate is replaced with lightweight aggregate, the weight decreases the concrete density …
To set the record straight, this blog compares LWC's ability to reduce design loads and aggregate cost compared to normalweight concrete (NWC). Evaluating Design Loads in Lightweight Concrete Structures. LWC weighs about 90-115 pounds per cubic …
Lightweight cementitious composite has been used in construction for thousand years. However, before the Second World War, lightweight concrete was …
The intrinsic properties of lightweight concrete (LWC) provides promising scope of using in structural purposes. Normal Weight Concrete has density 2400 kg/m 3 whereas LWC produces density ranging from 1400 kg/m 3 to 2000 kg/m 3. LWC can be produced by using light weight materials in concrete either as coarse aggregate or fine …
We recommend using polyurethane because it is significantly less expensive than replacing concrete slabs and it is an environmentally friendly process. Polyurethane expands into a lightweight material that fills voids, supports, and raises the concrete slab. Once the slab is lifted it is virtually impossible to detect, matching your ...
The units contain Big River Industries' expanded clay lightweight aggregate called Riverlite. "Lightweight block increases productivity even at the same labor pace, and workers are typically more efficient because the lighter block is less work intensive," Quinn said. The contractor used E-lite 24-inch-long lightweight concrete masonry ...
Such additives reduce the unit weight of concrete, which in turn reduces the weight of structures, reduces hauling costs and lessens worker fatigue – resulting in lower costs and potentially higher profits for …
ed concrete, also called cellular light weight concrete is produced by the mixing of Portland cement, sand including or alone fly ash, water and preformed stable .

Therefore, a lightweight concrete design primer was identified as a product that would be useful to advance the use of lightweight for bridge design. It was envisioned that the document would provide a concise summary of the full range of information needed to design a lightweight concrete bridge.
A structural light-weight concrete mix has a density of about 105 pounds per cubic foot compared to normal concrete with a density of 150 pounds per cubic foot. The light-weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less.
One of the main challenges in designing lightweight concrete is to adapt most of design, production and execution rules since they often deviate from normal weight concrete.
Take your concrete analysis to a new level with STAAD Advanced Concrete Design (formerly RCDC). Maximize your software investment by combining the power of popular structural analysis applications with robust concrete design.
In a concrete structure, there are two commonly used structural materials: concrete and steel. According to the unit weight of concretes, they can be classified into four categories, namely ultra-lightweight concrete, lightweight concrete, normal-weight concrete and heavyweight concrete.
Transit Mix Corp. has established itself as New York's industry leader in the delivery of high performance ready mixed concrete with superior customer service at a competitive price.
Taking advantage of the advanced material technology, NAMI's high strength lightweight concrete is composed of high performance cementitious paste and air voids with controlled size, showing high strength to density ratio and superior stability, suitable for production of precast building elements.
Lightweight concrete has a history of more than two-thousand years and its technical development is still proceeding. This review starts with a retrospective that gives an idea of the wide range of applications covered by lightweight concrete during the ...
Lightweight concrete finds diverse applications, including screeds, walls, insulation, and structural elements. Its advantages include reduced dead load, faster building rates, …
The cost of concrete is $119 to $147 per cubic yard for ready-mix concrete delivered up to 20 miles. Pouring plain concrete costs $5 to $10 per square foot.
Cellular lightweight concrete has several advantages associated with their applications: Termite proof and resistant towards freezing issues. 1. Lightweight: Cellular lightweight concrete is low on weight and thus it has a positive impact on weight management of building material and craning work.
To set the record straight, this blog compares LWC's ability to reduce design loads and aggregate cost compared to normalweight concrete (NWC). Evaluating Design Loads in Lightweight Concrete Structures. LWC weighs about 90-115 pounds per cubic foot (pcf) compared to NWC, which is about 145 pcf for LWC (using equilibrium density …
First, a review of smart concrete in terms of the current progress, benefits and challenges from 2015 to 2020 is expect to offer effective measures that can be used to improve the structural properties of the typical concrete.
