GET PRICELight weight concrete (foamed concrete) is a versatile material which consists primarily of a cement based mortar mixed with at least 20% of volume air. The material is now being used in an ever increasing number of applications, ranging from one step house casting to low density void fills. Light weight concrete has a surprisingly long history and was first patented in 1923, mainly for use as

GET PRICEElastic modulus of lightweight concrete with PVC aggregate was studied by Kou et al. (2009).Their results indicate that elastic modulus is reduced with an increase in PVC content. The 28-day elastic modulus were reduced by 6.1%, 13.8%, 18.9%, and 60.2% for PVC aggregate content of 5%, 15%, 30%, and 45%, respectively. This elastic modulus degradation is attributed to: (a) lower elastic modulus
GET PRICE03.07.2015· Structural light weight concrete: Concrete which is light weight and has sufficient compressive strength. 28 days compressive strength of more than 17Mpa and 28 days dry density not exceeding 1850 kg/m3. Generally has normal fine aggregates and lighter coarse aggregates. Workability is less due to water absorption by the aggregates. Drying shrinkage is more and less thermal
GET PRICELightweight concrete can be specified using the notation LC for the strength class, e.g LC30/33, which denotes a lightweight concrete with a cylinder strength of 30MPa and a cube strength of 33MPa. The lighter the concrete, the greater are the differences to be accounted for in the properties of the concrete. The tensile strength, ultimate strains and shear strengths are all lower than a

GET PRICEThorenfeldt, E reported that (2) Light Weight Aggregate Concrete has a faster hardening factor in the initial setting phase than conventional concrete, normally reaching 80 % of the 28 day strength within 7 days. The strength growth from 28 to 90 days is generally low and decreases with increasing concrete strength level. This is assumed to be a consequence of the strength limiting effect of
