🕑 Reading time: 1 minuteConcrete chemicals or admixtures are materials other than cement, aggregate and water that are added to concrete either before or during its mixing to alter its properties, such as workability, curing temperature range, set time or color. Some concrete admixtures have been in use for a very long time in concrete […]

The standard F2971 is being revised to capture all the manufacturing pedigree required for Additive Manufacturing

Concrete additives can reduce the water content required for a specific mix design without compromising its workability or strength. This enhances the overall quality of the concrete and contributes to its long-term durability. Reduced water content minimizes shrinkage and cracking, resulting in more resilient structures.

This research studies the effect of this admixture on concrete microstructure for several concrete specimens. This chemical admixture, which contains calcium oxide (CaO), chloride (Cl), and others ...

New Guide for Additive Manufacturing -- Wire Arc Additive Manufacturing. 1. Scope. 1.1 This guide provides an overview of the wire arc additive manufacturing (WAAM) process characteristics, benefits and limitations relative to other DED and conventional processing routes. This is intended to aid potential users in evaluating the …

Using fly ash in concrete reduces cracking, permeability, and bleeding, creating a dense, high-durability concrete that is resistant to sulphates and alkali-aggregate reactions. This concrete mix also requires less water and has a tendency to resist shrinking. However, using fly ash in concrete does come with potential problems.

Concrete admixtures (additives) enhances the properties of concrete for applications in construction with special requirements. Concrete additives are used to achieve desired workability in case of low water cement ratio, and to enhance setting time of concrete for long distance transportation of concrete. So, it is of much importance for a civil site …

For these drawbacks, the development of contemporary concrete technologies such as eco-friendly and affordable coconut fiber reinforced concrete needs more investigation.

Fly ash is used as a supplementary cementitious material (SCM) in the production of portland cement concrete.A supplementary cementitious material, when used in conjunction with portland cement, contributes to the properties of the hardened concrete through hydraulic or pozzolanic activity, or both.As such, SCM's include both pozzolans …
