Concrete structures are prone to earthquake due to mass of the structures. The primary use of structural lightweight concrete (SLWC) is to reduce the dead load of a concrete structure, which allows the structural designer to reduce the size of the structural members like beam, column, and footings which results in reduction of earthquake forces on the structure.

23-5-2020· Concrete BlockBackgroundA concrete block is primarily used as a building material in the construction of walls. It is sometimes called a concrete masonry unit (CMU). A concrete block is one of several precast concrete products used in construction. The term precast refers to the fact that the blocks are formed and hardened before they are brought to the job site.

ASTM C 90 classifies loadbearing lightweight concrete masonry as having an oven-dry weight of less than 105 pounds per cubic foot. Items to consider in creating lightweight block include: aggregates, variations in mix design, prevention of segregation, minimizing batch variation, mixing the concrete, increasing mix compaction, curing and drying, and handling finished units.

Experimental results also demonstrated that the coconut fibre concrete performed satisfactorily on the growth of cracks, crack widths compared with conventional concrete. Finally, it is concluded that the use of coconut fibre has great potential in the production of structural lightweight concrete especially in the construction of low-cost concrete structures.

Foam concrete, also known as Lightweight Cellular Concrete (LCC), Low Density Cellular Concrete (LDCC), and other terms is defined as a cement-based slurry, with a minimum of 20% (per volume) foam entrained into the plastic mortar. As mostly no coarse aggregate is used for production of foam concrete the correct term would be called mortar instead of concrete; it may be called "foamed …

12-6-2012· In this paper, we report the results of our investigation on the possibility of producing foam concrete by using a geopolymer system. Class C fly ash was mixed with an alkaline activator solution (a mixture of sodium silicate and NaOH), and foam was added to the geopolymeric mixture to produce lightweight concrete.

TYPES OF LIGHTWEIGHT CONCRETE: Using lightweight aggregates: This type is produced using lightweight aggregate such as volcanic rock or expanded clay.It can be produced with the use of naturally mined lightweight aggregates (bulk density in the range of 880 kg/m 3) or manmade lightweight aggregates like "Aardelite" or "Lytag" (bulk density 800 kg/m 3).

The recycle lightweight block (RLC) could be used as lightweight aggregate for making lightweight geopolymer concrete. The compressive strength increased with the increasing NS/NaOH ratio and temperature of curing but decreased with the increasing aggregate/ash ratio. The optimum L/A ratio was 2.4 and NaOH concentration was 10 M for maximum compressive strength.
