Mar 17, 2017 INTRODUCTION: Light weight concrete is a special concrete which weighs lighter than conventional concrete. Density of this concrete is considerably low (300 kg/m3 to 1850 kg/m3) when compared to normal concrete (2200kg/m3 to 2600kg/m3). Three types of LWC - Light weight aggregate concrete - Aerated concrete - No – fines concrete 3. 4.

Chapter 4 Proportioning Structural Lightweight Concrete

aggregate concrete made with structural lightweight aggregate as defined in ASTM C 330. The concrete has a minimum 28-day compressive strength of 2500 psi (17 MPa), an equilibrium density between 70 and 120 lb/ft (1120 and 1920 kg/m ), and consists entirely of lightweight aggregate or a combination of lightweight and normal-density aggregate.

Lightweight Aggregate Concrete an overview

Jan 01, 1992 Crushed lightweight aggregate concrete (LWAC) can also be used as an aggregate in concrete (recycled LWAC-aggregate) (European Union – Brite EuRam III, 2000).Crushed waste lightweight concrete block has been used successfully as recycled aggregates for making lightweight alkali-activated concrete using NaOH, sodium silicate and fly ash (Posi et al., 2013) with acceptable …

expanded polystyrene technology in construction

Mar 05, 2017 3. Use of lightweight aggregate as substitute to normal aggregate. The production process of lightweight concrete is cost-intensive due to complex machinery, chemicals and lightweight aggregate to be used. The idea of using polystyrene as a substitute for the expensive lightweight aggregate (or the air bubbles) was introduced.

Chapter 2 Asphalt and Asphalt Paving Materials

AGGREGATES Aggregates (or mineral aggregates) are hard, inert materials such as sand, gravel, crushed stone, slag, or rock dust. Properly selected and graded aggregates are mixed with the cement-ing medium asphalt to form pavements. Aggregates are the principal load-supporting components of an Asphalt Concrete pavement.

STUDY OF LIGHTWEIGHT CONCRETE BEHAVIOUR

The lightweight aggregate can be natural aggregate such as pumice, scoria and all of those of volcanic origin and the artificial aggregate such as expanded blast-furnace slag, vermiculite and clinker aggregate. The main characteristic of this lightweight aggregate is its high porosity which results in …

What Is Lightweight Aggregate Concrete And Its Uses

The lightweight aggregate is a kind of coarse aggregate which is used in the production of lightweight concrete products like concrete block, structural concrete, and pavement.. The shape of the lightweight aggregate used in concrete can be cubical, rounded, angular, or of any other shape.The shape and texture can directly affect its workability. The compressive strength level which is ...
