Derived from burning coal, fly ash is a valuable additive that makes concrete stronger, more durable and easier to work with. Fly ash aids the formation of cementitious compounds to enhance the strength, impermeability and durability of concrete. Two main classes of fly ash are used in concrete, Class F, and Class C.

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.

Some common additives used to enhance concrete strength include: Silica Fume. Silica fume is a byproduct of silicon metal production and is added to concrete mixes as a pozzolan. It reacts with calcium hydroxide in the cement paste to produce additional calcium silicate hydrate (C-S-H) gel, resulting in denser and stronger …

Concrete mixes of 9 compositions were made by adding 0%, 2.5%, 5%, 7.5% and 10% of mineral additives by weight of cement. The tests revealed that the addition of mineral additives up to 10% increases the compressive strength of concrete. ... Additive of concrete (aluminosilicate) is a pozzolanic concrete additive based on …

The high water reducing additives/superplasticizer are synthetic water-soluble organic substances that significantly reduce (up to 40%) the amount of water needed to achieve a certain consistency of concrete (of higher compression, very workable) [2]. This effect can be used in two ways:

The bulk density of ordinary concrete is about 23 kN/m 3.The concrete having bulk density between 5 to 18 kN/m 3 is known as lightweight concrete and it is prepared from the following materials:. Binding material: The ordinary Portland cement and its varieties can be used as binding material. If local binding material such as lime-slag, lime-cinder, etc. is …

Our construction projects: With the help of the ICL additive (ICL-CA) we have developed, the compressive and flexural strength, watertightness, fire resistance, thermal and sound insulation capacity of lightweight concrete with high polystyrene beads can be significantly increased, as well as load-bearing structures from them.

Accelerating additives: Accelerating additives speed up concrete's setting time and can help lock in the strength gains concrete develops early on. Corrosion inhibitors: These additives are primarily used to reduce the amount of corrosion and subsequent expense of maintenance on structures reinforced with steel or other embedded metals.

The normal weight coarse aggregate (NCA) collected from local sources in Riyadh, Saudi Arabia was used in experimental work to produce a normal weight concrete (NCAC) control mix. Additionally, a local volcanic lightweight aggregate (VLA) was used for the reference mix of local lightweight concrete (VLAC).

A ternary lightweight concrete mixture was also prepared modifying the control lightweight concrete by replacing 20% of cement with fly ash and 10% of cement with silica fume. Two normal weight concrete (NWC) were also prepared for comparison purpose. Fly ash and silica fume are used for economical and environmental concerns.
