Stress–Strain Characteristics of Natural and Recycled Aggregate Concrete with Waste Foundry Sand and Additives
The utilization of waste materials as an alternative to constituents of concrete has been widely investigated to prove their utility and protect the environment from unplanned disposal. The stress–strain characteristics of concrete are important to understand its behavior under compressive and tensile loads. This experimental study investigated the compressive and splitting tensile stress–strain characteristics of natural and construction waste concrete with different admixtures. The stress–strain characteristics under compression and tensile loads for normal concrete deteriorate on substitution of natural aggregate with construction waste aggregate but improve with the use of waste foundry sand substituent. Use of several additives such as silica fume, superplasticizer, and fiber; with waste foundry sand substituent improved the compressive and splitting tensile characteristics of concrete; optimum being recorded on fiber addition. The development of strength with age for waste aggregate concrete shows a similar trend as that of natural aggregate concrete. Thus, waste materials obtained after refining of construction waste and foundry waste can be used in concrete without compromising much with the stress–strain characteristics of concrete under compression and tension.
