What is the meaning of GGBS in construction field?
Cement addtive called GROUND GRANULATED BLASTFURNANCE SLAG
Advantage of using ggbs in concrete?
because is needs the Ca-OH that is produced from the cement reaction with water to start the hardening but if you added Ca-OH to water it may be used a cement but its very expensive with no much difference in strength
What are the ingredients in concrete?
That depends on the mix, there are hundreds of different mixes of concrete. A basic mix of concrete (say a blended RC25 mix) has 1000kg of sand, 1000kg of stone, 150kg of OPC cement, 125kg of GGBS slag, 1.3lt of WRA and 75lt of waters PER CUBIC METER. Regards Colin, a Tarmac concrete batcher.
What is the difference between opc and pozzolanic cement?
first a bit of background.... A pozzolanic material is a material that will set hydraulically (with the addition of water) when calcium hydroxide is present. The good thing about this, is that when Cement hydrates and hardens it produces a few chemicals Calcium Silicate hydrate (CSH) which is what gives cement most of it's strength, and Calcium Hydroxide. This calcium hydroxide is exactly what we need to set a pozzolanic material and hence we can mix them in certain quantities to reduce the need of cement, use waste materials, and improve the qualities of the cement to some degree. Now back to the question..... A protland pozzolano cement (PPC) is a cement with an addition of one of this pozzolanic materials. i.e. pulverised fly ash (PFA), ground granulated blast furnace slag (GGBS), silica fume, A Portland slag cement is a mix between Portland cement and and a pozzolanic material derived from blastfurnace slag.
What is full form of GGBS?
ground granulated blast furnace slag
What is the meaning of GGBS in construction field?

Is using GGBS in concrete more expensive?
Using Ground Granulated Blast Furnace Slag (GGBS) in concrete can be more expensive than traditional Portland cement due to the higher cost of the material and the processing involved. However, GGBS can enhance the durability and longevity of concrete, potentially leading to lower maintenance and lifecycle costs. Additionally, its use may be incentivized by sustainability goals, offsetting initial costs over time. Ultimately, the economic impact depends on project specifications and local material availability.
What is Portland slag cement and slag cement?
Portland slag cement is a type of blended cement that combines Portland cement with ground granulated blast-furnace slag (GGBS), a byproduct of steel production. This mixture enhances the durability, strength, and resistance to sulfate attack of concrete while reducing the environmental impact of cement production. Slag cement, on the other hand, refers specifically to the use of GGBS as a partial replacement for Portland cement in concrete, contributing to improved performance in various applications. Both types of cement are used in construction to create more sustainable and resilient structures.

How do you know the purity of cement?
The purity of cement is typically tested using physical and chemical analysis methods. This includes examining factors such as composition, particle size distribution, setting time, and compressive strength. Quality control processes, such as X-ray fluorescence and wet chemistry tests, are commonly used to ensure the purity and quality of cement.
70 cubic mitre of concrete how many cubic mitre of sand gravel and cement to make concrete of grade 15?
I cant accuratly help you with the cement content but you need about 1 ton of sand and 1 ton of stone for every cubic meter of concrete. The cement content would depend on what you are using the concrete for. At 15 newtons of strength you would ( and this is just an educated guess) need about 95kg of OPC cement, 85kg of GGBS slag, 1.5lt of WRA (water reducing agent) and about 70lt of water to gain a 50mm slump per cubic meter. If I were you I would get it ready mixed. 70 Cube is a LOT of cocrete. Ready mixed 15 Newton concrete is about £75 inc vat per meter delivered. Regards Colin, a Tarmac concrete batcher.
