Properties of Light Weight Concrete The most significant property is reduced weight at no sacrifice in strength. Structural lightweight concrete available today are rotary kiln expanded shale, clay or slate (roughly 80% of structural use) and sintered expanded shale or clay (20%) provides the same compressive strength as normal weight aggregates with approximately the same(…)

LIGHTWEIGHT CONCRETE WITH APPLICATIONS
Light weight concrete with Applications Concrete is the most widely used man-made construction material. It is obtained by mixing cement, water and aggregates (and sometimes admixtures) in required proportions. The mixture when placed in forms and. allowed to cure becomes hard like stone. The hardening is caused by chemical action between water and the cement(…)
DESIGN OF LIGHTWEIGHT AGGREGATE CONCRETE
Mix design methods applying to normal weight concrete are generally difficult to use with light weight aggregate concrete. The lack of accurate value of absorption, specific gravity, and the free moisture content in the aggregate make it difficult to apply the water/cement ratio accurately for mix proportioning. Light-weight concrete mix design is usually established by(…)
CELLULAR LIGHTWEIGHT CONCRETE–FLY ASH BASED
Cellular Lightweight Concrete (CLC) is one of the recent emerging technology in making concrete. It has many advantages when compared to the normal conventional concrete. Fly ash is considered as one of the waste industrial product that cannot be easily disposed. It solves the problem of disposal of flyash and at the same time it(…)
QUALITY CONTROL OF LIGHTWEIGHT CONCRETE
Quality control of lightweight concrete To get good normal weight concrete, an engineer writes a good specification and sees that concrete quality is assured by proper control procedures at the job. With lightweight concrete, the engineer specifies a C330* aggregate and the 28- day strength and air-dry weight necessary to meet design requirements. Slump and(…)
ALL ABOUT LIGHT WEIGHT CONCRETE
LIGHTWEIGHT CONCRETE The use of LWC (Lightweight concrete) has been a feature in the construction industry for centuries, but like other material the expectations of the performance have raised and now we are expecting a consistent, reliable material and predictable characteristics. Structural LWC has an in-place density (unit weight) on the order of 90 to(…)
