Alkali-silica reaction, ASR is a type of concrete degradation. Three conditions are necessary for ASR to occur such as a reactive form of silica or silicates, available alkali and moisture. ASR gel formation is possible when these conditions are present.
Though, the existence of ASR gel does not necessarily mean concrete damage will occur. Impairment can be caused as the ASR gel absorbs moisture and swells. This leads to extreme pressure from expansion. It typically takes years to develop and results in cracked aggregates.
Near-surface alkali reaction gel is another cause responsible for debonding and blistering of epoxy coatings. It occurs closer to the surface, involves smaller aggregates. It takes less time to develop, and is associated with a low-permeance floor coating. This also requires the presence of reactive silica or silicates, available alkali, and moisture to form the gel. The failure leads to blistering in the low permeability surface coating applied to the concrete.
The occurrence of excess alkali from NSAR at the concrete surface creates disproportion of solute. This generates an osmotic cell leading to attraction of more water. The water is pulled through the concrete. This acts as a semi-permeable membrane and collects on the concrete surface. The existence of the relatively impermeable coating covering traps the excess moisture. This results in blistering of the coating.
Lithium compounds have been used in concrete to inhibit ASR from causing degradation. Also, to protect the surface by aiding in the concrete densification.
When performing investigations of blistering and other failures of Epoxy Flooring systems, it is important to observe and take into account a number of factors, such as, Lithium silicate was applied to the concrete surface and the cracks present in the field core samples were parallel or sub-parallel to the surface.

Epoxy formulations have been an important part of the construction industry for half a century. Epoxy flooring has become quite popular due to various benefits it offers over other kind of flooring. Below are few things which you need to know about this flooring.
Have you ever thought that what is the secret behind the high performance of garage epoxy flooring Gilbert? Epoxy resins are the secret behind the excellent performance, which is the core material of formulation which consist primers, top-coats and sealants. Due to these resins, epoxy efficiently works as floor finishes, fire retardants, protective coats, waterproofing and damage resistant paints.
Another thing which you need to know is that, epoxy coatings can be applied over many surfaces. It can work on concrete, steel and almost every other kind of surface. Specific flooring needs specific coating systems which is done by selecting the required substrate.
Many of us don’t know that epoxy resin molecules are cross linked and they are almost impermeable. A unique reaction takes place that produces cross linked epoxies when exposed to amines. This reaction is the reason behind creation of coatings which are highly resistant to water, air intrusion or chemical and corrosion resistant surfaces.
Epoxies can be combined with many other kind of materials which further increase the performance. Epoxy-amine systems, aliphatic epoxy systems, epoxy-sulfide systems and hybrid epoxy systems are some of the common systems which can be created with epoxy. With amine, one can get a glossy surface with better adhesion, this combination is widely used in industrial floor coatings.
This kind of flooring is highly durable due to its various properties and become an ideal choice for residential as well as industrial needs.

There are many reasons due to which epoxy garage floors are gaining popularity. When we talk about ordinary floors, they are just plain dull grey concrete and such floors becomes even more ugly over time due to oil, grease and chemical stains. Having an epoxy garage flooring Gilbert ensures years of services, durability and will resist most of the stains effectively to give you a well finished and vibrant surface.
Below are three most common garage epoxy flooring Phoenix systems.
Each of the type has its own properties and strengths. Based on their usability, you can have 'good', 'better' and 'best' types of epoxy garage floor systems.
The Good system
The epoxy polyurethane solid color system lasts for approx. 5-7 years without any maintenance but requires a coat of pigmented polyurethane. This garage floor usually comes with two coat thin film systems with the thickness range of 4-20 mils. It is applied either by roller of airless sprayer.
The Better system
The epoxy Chipstone system last for approximately 7-12 years without any maintenance and post that coat of clear polyurethane is required. The epoxy garage floor system consists two components— a pigmented primer coat of epoxy and another is pigmented color coat of partial broadcast with vinyl chips. The thickness is around 20-30 mils.
The Best system
When we talk about the best system then epoxy Granitex system comes in picture which last for 12-15+ years without any maintenance and need a coat of polyurethane thereafter. This one also contain two components— one is pigmented primers and the second one is pigmented color coat with full broadcast of vinyl chips.
On the basis of above information, you will be able to select the best epoxy floor for your needs.

Epoxy floor coatings have emerged as great choice due to its high durability and low maintenance. Another benefit is the customization, you choose from a variety of color options and can go for textured surface or smooth finish. It totally depends on the personal preferences. Below are few important things about the garage epoxy flooring Gilbert that you need to know.
You must know that the secret behind the high performance epoxy coating is epoxy resins. The epoxy resins are the core or main material of the formulation like top-coats, primers and sealants. These resins make it feasible for epoxy floor coatings to perform well even in extreme conditions.
You can apply the epoxy coatings to many surface types and this makes epoxy one of the popular choices for commercial or residential use. Specific floor applications need specific coating systems that is mainly dictated by the material used for substrate. Epoxy can work well in concrete, steel or nearly every type of surface.
Another property of epoxy coating is that it can combine with other kind of material for increased performance. Epoxy-amine system, aliphatic epoxy systems, epoxy-sulfide system are some of the common coating systems. With amine, one can achieve glossy surface, better adhesion and beautiful appearance. Epoxy systems work really well with acrylics and alkyds.
When you think of heavy duty floors then epoxy emerges as the winner as the coating is resistant to various kind of damages. This is the reason that epoxy is majorly applied to those areas that are continuously exposed to damage-inducting agents like garage, manufacturing plants, warehouses, airplane hangars and heavy machinery floors.
When it comes to garage epoxy floor ideas Gilbert then you will get abundant option but only a right service provider will be able to guide you and help you take right decisions.
