ESCS Product Expanded shale, expanded clay and expanded slate (ESCS) lightweight aggregate is prepared by expanding select minerals in a rotary kiln at temperatures over 1000#176; C. The production and raw material selection processes are strictly controlled to ensure a uniform, high quality lightweight aggregate. ESCS gives designers greater flexibility in creating solutions to meet
Lightweight aggregate concrete is prepared by using lightweight aggregate or low density aggregate such as volcanic pumice, clay, slate, shale, scoria, tuff and pellite. Concrete is considered to be lightweight is the density is not more than 2200 kg/m3, when compared to normal concrete which is kg/m3 and a proportion of the aggregate, should []
According to ASTM structural lightweight concretes compressive strength should be greater than 2500 psi (17 MPa).. Lightweight concrete based on the method of production is classified as below:. Lightweight aggregate concrete, Aerated concrete, Nofines concrete. Out of this lightweight concrete and aerated concrete is more uses than nofines concrete.
#0183;#32;LECA (Lightweight Expanded Clay Aggregate) is base material to Produce lightweight concrete and precast elements, as well as many other products and purposes, please visit our website
LECA has an approximately round or potato shape due to circular movement in the kiln, and is available in different sizes and densities. LECA is used to make lightweight concrete products, building materials and other uses. A 020 mm lightweight expanded clay aggregate can be mixed with NHL for use with concrete floors as an insulating subbase
Leca#174; Lightweight Aggregate (LWA) is used extensively as a lightweight fill for civil engineering and structural applications including highways, bridges, rail, marine, chemical biofilters, water filtration, retaining walls, green roofs, sports centres...

#0183;#32;Choi et al. (2006) studied the possible of using Light expand clay aggregate (LECA) to manufacture highstrength lightweight selfcompacting concrete. According to their obtained results, the compressive strength was more than 40 MPa for all mixtures at 28 days.
#0183;#32;This paper determines mix proportions of highstrength structural lightweight concrete (HSSLWC), which reduces the weight of concrete by using expanded aggregate clay (Leca). In order to produce HSSLWC, mineral and chemical admixtures have been used along with limestone that reduces porosity and increases strength. Tests for specific gravity, and compressive, indirect tensile
Lightweight expanded clay aggregate (Leca) has stood the test of time in Acotec wall production. Leca replaced the wood chip as a concrete raw material in Acotecs early years of the late 1980s. Since then this economical partition wall technology has successfully penetrated into Asian construction markets.
LECA lightweight concrete block: LECA back is produced by mixing of Leca aggregates, Cement, sand and water. Using of Leca aggregate decreases the concrete density. Advantages: Lightening up to 30% of dead load; Self thermal amp; Sound Insulation; Appropriate Behavior in Earthquake
Expanded Clay Aggregate Precast Concrete Segments ECA LECA. But the recently Lightweight Expanded Clay Aggregate (LECA) has been introduced instead of coarse aggregate to make concrete have light weight Lightweight concrete is awkward to make a case belong to a unique category material However LWC (light weight concrete) has clear edges and the plunge in the total expense
The concrete mix was determined by trial mixes so as to obtain the highest possible volume fraction of coarse aggregate using 1:1 mortar (W/C=30%).The compressive tests were carried out on 10
lightweight aggregate concrete. For this purpose, in a structural lightweight aggregate concrete made of expanded clay, the lightweight aggregate was substituted with OPS in 0, 25 and 50% by volume. Properties such as compressive strength under different curing conditions, as well as density, splitting tensile and exural strengths, modulus
split dense aggregate concrete units; lightweight clay units, vertically perforated; special shape units. Generally these new products are well developed and studied, but their cost is yet higher than traditional ones. Concerning lightweight concrete, in the beginning of the 90s the unique Portuguese lightweight expanded clay aggregate
Leca#174; Lightweight Expanded Clay Aggregate is used extensively in new buildings, the restoration of historical buildings and domestic renovation projects Inc Underfloor Insulation.. LECA#174; LWA can be used in all elements of construction from foundations to rooftop. It is primarily used in internal and external masonry walls, both in blocks and mortar as well as providing insulating layers in
