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
One advantage of using asphalt as the wearing course of a road is its flexibility, which allows it to better withstand temperature fluctuations and heavy loads without cracking. In contrast, one advantage of using concrete is its durability and longevity, as it can last longer than asphalt under similar conditions and typically requires less maintenance over time.
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 advantage of using an PLM
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.
allows the use of higher slump of concrete which results in stringer concrete

I think you are talking about embedding steel rods (rebars) in concrete, right? This would make the concrete much stronger. It is called reinforced concrete, and you can make all sorts of structures with it, something that you can't do with ordinary concrete. Though, I am not even sure anyone is using non-reinforced concrete nowadays.

ground granulated blast furnace slag
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.
they give a goodstrength for concrete
