Abstract
Dr Lo specializes in the production, design, development and application of lightweight aggregate and concrete products from high strength structural lightweight concrete to ultra light heat/sound insulation block. They are very versatile and therefore can be used for in-situ casting, pre-fabrication, roof insulation, maintenance and renovation work. Compared with normal weight concrete of 2500kg/m3, lightweight concrete weighs only 800-1800kg/m3 but with the compressive strength ranges between 5-50MPa. Its permeability and anchorage properties are superior to aerated or foam concrete. Batching and production of lightweight concrete is similar to normal concrete. The mixing, transporting, casting and curing techniques are the same as normal concrete.

Features
•User-friendliness : ready-mixed, pre-bagged lightweight concrete
•Reduced foundation load of structure
•Enhanced speed of construction
•Minimized craneage load

Applications
•Pre-fabrication
•Roof insulation
•Sound insulation
•Lightweight block
•Infilling
