Eco-Friendly Alternatives To Traditional Concrete

Posted on July 18, 2019. Concrete is a mixture of cement, gravel, sand, water and a range of aggregates. With about 10 billion tons of concrete produced every year, it is the most consumed substance in the world, second only to water.. It is also the world's most widely used material for construction - from bridges to large buildings, concrete forms the very foundation of our infrastructure.

Strength - Penn State College of Engineering

However, aggregate characteristics other than strength, such as the size, shape, surface texture, grading and mineralogy are known to affect concrete strength in varying degrees. Size: The maximum size of a well-graded coarse aggregate of a given mineralogy can have two opposing effects on the strength of normal concrete.

Recycled Concrete Aggregates: A Review | International

Improvement of tensile strength with the addition of RCA would usually be associated with an improved elasticity; however, because the "recycled aggregates are more prone to deformation than raw aggregates," the weakness of the aggregate reduces the Young's modulus for concrete when RCA is used (Exteberria et al. 2007). Generally, Young
