What is poly concrete?
Polymer concrete is an aggregate mixture that uses some type of epoxy binder to cure and harden into place. A polyester, vinyl ester, or normal epoxy mixture is often used, but polymer concrete can be made with many kinds of polymer resins that allow the concrete to be poured or troweled and then hardened.

Properties of Polymer Cement Concrete. 1. Highly Impermeable. The polymer phase in the concrete will help reduce the porosity and microcraks that are formed in cement matrix. This acts as an additional binding material other than the Portland cement used. 2.
What is the purpose of a prepolymer in Portland cement?
To the Portland cement a prepolymer (monomer) of a dispersed polymer is incorporated to make PCC. This combination creates a polymer network in situ during the curing process of the concrete. The use of typical vinyl monomers can interfere with the hydration process or can get degraded. So the use of prepolymers are found more effective as perform the function required. In order to improve the mechanical properties of the PCC, these prepolymers can be added in higher proportions. As this concrete property is based on the incorporation of a polymer, special care and attention is taken while adding the latex. The emulsion employed increases the lubrication properties of the mix. Hence, only less amount of water is required for workability of the mix.

Polymer concrete has historically not been widely adopted due to the high costs and difficulty associated with traditional manufacturing techniques. However, recent progress has led to significant reductions in cost, meaning that the use of polymer concrete is gradually becoming more widespread.
What are the properties of Portland cement?
The exact properties depend on the mixture, polymer, aggregate used etc. Generally speaking with mixtures used: 1 The binder is more expensive than cement 2 Significantly greater tensile strength than unreinforced Portland concrete (since polymer plastic is 'stickier' than cement and has reasonable tensile strength) 3 Similar or greater compressive strength to Portland concrete 4 Faster curing 5 Good adhesion to most surfaces, including to reinforcements 6 Good long-term durability with respect to freeze and thaw cycles 7 Low permeability to water and aggressive solutions 8 Improved chemical resistance 9 Good resistance against corrosion 10 Lighter weight (slightly less dense than traditional concrete, depending on the resin content of the mix) 11 May be vibrated to fill voids in forms 12 Allows use of regular form-release agents (in some applications) 13 Product hard to manipulate with conventional tools such as drills and presses due to its density. Recommend getting pre-modified product from the manufacturer 14 Small boxes are more costly when compared to its precast counterpart however pre cast concretes induction of stacking or steel covers quickly bridge the gap.
