An important question always is how much this will cost. Lightweight aggregate concrete is about $20 to $30 per cubic yard higher than a normal weight mix. For internal curing, you may only be replacing about a third of the aggregate with lightweight so it may only add an extra $10 per cubic yard.

Nowadays, lightweight aggregate concrete is becoming more popular due to its versatile properties. It mainly helps to reduce the dead loads of the structure, which ultimately reduces design load requirements. The main challenge associated with lightweight aggregate concrete is finding an optimized mix per requirements. However, …
For that reason, lightweight aggregate properties and the various types of lightweight concrete are discussed in detail with a special focus on current standards. The review is based on a background of 25 years of practical and theoretical experience in this field. One of the main challenges in designing lightweight concrete is to adapt most of ...
This paper aims to examine the effect of surface roughness of lightweight aggregate particles (LWA) on the strength and permeation characteristics of lightweight aggregate concrete (LWAC). Changing the smooth surface texture of LWA particles was achieved by applying surface polishing to make rough texture of the aggregate particle …

We have been working in light weight concrete research for more than 10 years. The research work can be put into practice by researching and developing in every aspect such as production machinery, Air Bubbles and mix-design of Cellular Concrete or We call new Cell Crete mean a concrete that is density Lower than general concrete with …
Two lightweight aggregate concretes, SLWC35 and SLWC50, of 35 and 50 MPa 28 day cube compressive strength were cast. The concrete specimens made with lightweight coarse aggregates and a dune sand were continuously cured in water for one or 7 days and then exposed to predominantly hot and humid seaside ambient conditions …
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 …
Lightweight aggregate is a type of coarse aggregate that is used in the production of lightweight concrete products such as concrete block, structural concrete, and …
The product is an excellent alternative to natural quarried aggregate, being strong, light and consistent. Sintered Flyash light weight aggregate substitutes natural stone aggregate/chips in Concrete, reducing dead weight. It can also be used in production of light weight precast Concrete Blocks, for use in load and non-load bearing elements.
