Heavy and difficult to transport – Concrete is …
The Advantages of a Polished Concrete Floor. Image source: WA Design Architects. Polished concrete has a stark look that makes small spaces seem large. There are no grout lines like with tile or joining seams like with floorboards, which means that a polished concrete floor is just one unbroken sheet of material.
Estimates suggest that the presence of 1% muscovite mica causes a reduction of the concrete strength by approximately 5% and it has relatively poor bond strength with cement paste.
According to the 2017 Mica Action Group and the Report of the Expert Panel on Concrete Blocks, Mica has the ability to absorb and store water and results in a disproportionate amount of water in ...
The first reason why concrete is an inferior product to NatraTex products is because concrete is an extremely expensive material to apply and maintain. Not only does concrete require a more base material to lay — especially in regards to premium quality concrete — it also requires specialist equipment to apply the concrete to the road surface.

The World of Concrete: Advantages and Limitations Written by Barkman Concrete Published on November 16th, 2011 Did you know that concrete is the most commonly used construction material in the world and that around 7.5 billion cubic meters are cast every year worldwide.
The concrete is only allowed to be transported to the construction site once it is approved after tests. It is also known as wet batch plants. However, the process is time-consuming and not always recommended. Advantages of Ready Mixed Concrete. 1. One of the biggest advantages of RMC is that concrete is produced under controlled conditions.
Mortar mixtures contained 20 % of mica (Mi), 4 % of illite (I) and 4 % of montmorillonite (M) as replacement of standard sand caused approximately a 50–60 % reduction in mortar strength at 28-days when compared to mortar mixtures prepared with standard sand (Table 18.8).According to results obtained, mortar containing 4 % illite (I) …
