Lightweight Concrete Using Lightweight Aggregates from Construction and Demolition Wastes—Production and Properties
In recent decades, construction and demolition wastes (CDW) have caused serious environmental problems for many countries in the world, including Vietnam. Those problems can be solved by making use of CDW as building materials. This paper focuses on a research work, where CDW, in the form of a mixture of brick and mortar, are burned into lightweight aggregates (LWA), which are used for making lightweight concretes (LWC). The paper describes how LWC are produced using the LWA from CDW and presents their mechanical properties, including compressive strength and elastic modulus by experimental tests. It has been shown that it is possible to use LWA recycled from CDW to make LWC with the density less than 1800 kg/m3 and 28 day-compressive strength up to 25 MPa. The mechanical properties of LWC are significantly influenced by the volume and size of the LWA used in the experiments. In practical application, these LWCs are expected to be used for making LWC slabs and walls to use for the construction of buildings.
