LECA Main Advantages
Applying LECA insulating blocks drop the rate of fuel and electricity consumption and are the best way for optimizing energy consumption.
With advanced acoustic specifications, LECA sound insulation goes beyond other building materials. Sound insulation of a one layer LECA block wall ranges from 46 to 53 db which is appropriate for all kind of building functions.
LECA building blocks are non-combustible building material and classified as reaction to fire Euro class A1 (no contribution to fire).
Lightening the structure significantly decreases building cost and lowers earth quake threaten.
Leca: What is it
Leca is initial letters for light expanded clay aggregate.
Lightweight Precast Elements and Masonry Units
LECA Precast Elements and Masonry Units is a construction accelerator, time ,labor and material saving. LECA building blocks are solid or hollow blocks of lightweight aggregate concrete. The base product is LECA.
Screed, Flooring and Roofing
Leca makes a smart package of lightweight elements, thinner section, better fire rate, insulating roof, improved seismic structural response, less reinforcing and lower foundation cost. LECA use assures all necessary essential factors for comfort, during summers or winters.
Light Weight Concrete (LWC)
In addition to the weight savings, lightweight concrete has substantially better fire-resistant qualities than normal weight concrete, significantly lower heat transmission, remarkable moisture resistance and more durability. It protects steel reinforcement from the corrosive action, salt water and severe environments.
Lower weight reduces seismic forces, reinforcing and pre-stressing steel, increase live load capacity for Bridges and Marine Structures. Moreover, with Low permeability, it is Highly Durable to freezing and thawing and chloride ions. Owing to LECA long term water absorption, LECA will act as an internal source of water for internal curing which will help to avoid shrinkage and improve long term strength.
Internal Curing of Concrete
Internal Curing (IC) for cement is a practical way of supplying additional water throughout the concrete mixture. In other words, achieving better hydration and less waste of valuable cement. This is done by consuming absorbed water in Light Expanded Clay Aggregate (LECA) which is replacing some of the conventional aggregates in the mixture.
Internal curing of concrete
Internal Curing: “supplying water throughout a freshly placed cementitious mixture using reservoirs, via pre-wetted lightweight aggregates, that readily release water as needed for hydration or to replace moisture lost through evaporation or self-desiccation”
