Lightweight Concrete (LWC) Structuralgrade lowdensity aggregate • Has absorption coefficients of 5 to more than 25 . Recognizing and accounting for this effect is essential in mix design and fabrication of LWC. The absorbed water is available for longterm hydration leading to an internal curing effect.

Our system is designed to help you save on labors overheads and mobilization cost without spending more on material costs so you can
This presentation gives overview of different Lightweight aggregates and its influence in concrete
For drying shrinkage of lightweight aggregate concrete values for normal weight aggregate concrete should be increased by the following factors • when 28day mean strength ≤22 MPa characteristic cylinder strength ≤16 MPa or characteristic cube strength ≤18 MPa. •
Relative Density of Lightweight vs. Normal Weight Aggregate Relative density for rotary kiln expanded lightweight aggregates Range from to Relative density for normal weight aggregates Range from to Twice the volume for same mass Half the mass for the same volume 1 lb. of each aggregate 3
made with structural lightweight aggregate as defined in ASTM C 330. The concrete has a minimum 28day compressive strength of 2500 psi (17 MPa) an equilibrium density between 70 and 120 lb/ft³ (1120 and 1920 kg/m³) and consists entirely of lightweight aggregate or a combination of lightweight and
Lightweight aggregates serve the function of dimensionally stable aggregates with suitable density and water absorption and can be prepared from sludge through sintering processes (Huang et al. 2001 ). Huang and Wang (2013) manufactured these aggregates and investigated their structural and nonstructural properties.
Classification of Aggregates Penn State Engineering. Classification of Aggregates The variability in density can be used to produce concrete of widely different unit weights see Table 1 The most common classification of aggregates on the basis of bulk specific gravity is lightweight normal weight and heavyweight aggregates.

BS sieve. shall not exceed 10 by 10 mm BS sieve. 8. 2. Preparation of concrete without the smooth (rough concrete) Lightweight concrete such as is obtained when the fine aggregate (sand) is not used and the concrete mix of cement water and coarse aggregates. Concrete can be used for structural purposes and not to bear burden to bear a load.
Light Weight Concrete. • The first commercial scale production of light. weight aggregate manufactured in Kanas city in. 1917 named as "HAYDITE". f• Other expanded clay aggregates such as. "GRUELITE" "TERLITE" "ROCKLITE" were. marketed by various American firms. • In 1930 hollow globular burnt clay particles.
CHAPTER 7 ENGINEERING PROPERTIES OF STRUCTURAL LIGHTWEIGHT CONCRETE Introduction Comprehensive reports detailing the properties of Lightweight Concrete and lightweight aggregates have been published by Shideler 1957 Reichard 1964 Holm 1983 and 2006 Carlson 1956 and Valore 1956 1980.
What if we could find a lightweight building material that has the quality or durability and strength of rock contain freezing thawing properties and thermal conductivity as well. How could we achieve this We would have to change the composition the weight or density. One way is to incorporate a lightweight aggregate.
Lightweight concrete is a mixture made with lightweight coarse aggregates such as shale clay or slate which give it its characteristic low density. Structural lightweight concrete has an inplace density of 90 to 115 lb/ft³ whereas the density of regular weight concrete ranges from 140 to 150 lb/ft³. This makes lightweight concrete ideal
Masonry units made with STALITE are significantly lighter and easier to install. Compared to heavyweight units of the same size weight reductions of up to 30 can be achieved. Unlike aggregates made from byproducts and waste STALITE masonry materials are pure and produced under carefully controlled conditions to assure performance. In addition the superior strength of STALITE particles make
