Incorporation of Phase Change Materials in Lightweight Aggregate Concrete

Prediction of Lightweight Aggregate Concrete Compressive Strength

Nowadays, the better performance of lightweight structures during earthquake has resulted in using lightweight concrete more than ever. However, determining the compressive strength of concrete used in these structures during their service through a none-destructive test is a popular and useful method.  One of the main methods of non-destructive testing in the assessment of compressive strength...

Beneficial Reuse of Locally-available Waste Materials as Lightweight Aggregate in Lightweight Concrete

Properties of Green Lightweight Aggregate Concrete

With increasing concern over the excessive exploitation of natural aggregates, synthetic lightweight aggregate produced from environmental waste is a viable new source of structural aggregate material. The uses of structural grade lightweight concrete reduce considerably the self-load of a structure and permit larger precast units to be handled. In this paper, the mechanical properties of a str...

A study of the durability of recycled green building materials in lightweight aggregate concrete

In this study, waste tire powder and waste liquid crystal display (LCD) glass sand are used as recycled materials. With a fixed water to binder ratio (W/B = 0.4), the use of fly ash and slag as cementreplacement materials. waste tire powder and waste LCD glass sand, which passed the sieve screen size # 30(0.595 mm), were used to replace fine aggregates at 0%, 5% and 10% in producing lightweight...

Potential applications of phase change materials in concrete technology Dale

In internal curing, pre-wetted lightweight aggregates (LWA) serve as internal reservoirs to supply the extra water needed by the cementitious and pozzolanic components of the concrete during their hydration processes. Due to their porous nature and reasonably high absorption capacity, the LWA can also be filled with other materials, such as phase change materials (PCMs). In this paper, three po...
