Cement Modifier

Modifying cement formulations with polymers provides many important properties that make a variety of niche applications possible, including concrete patch and repair, decorative cement overlays, ceramic tile adhesives, and many others. To get the performance desired for any of these applications, it helps to understand some of the basics of why polymers are added to cement formulations.

The first thing to understand is that polymers are primarily used to modify mortars (portland cement + water + sand aggregate), not concrete (mortar + larger aggregates such as gravel or stone), due to the relative cost involved. The main exceptions are polymer-modified concrete for bridge deck overlays and road repair work. Most polymer-modified cement applications involve mortar that is not more than an inch or two thick. But let’s start with the basics.

Polymers improve mortars in four main ways:

1. More extensive cement cure. Cement/concrete strength depends on proper curing, a chemical reaction (hydration) between water and cement that causes crystals to grow and wrap around the mix components. During the early stages of cure (roughly the first five to seven days), there must be enough water to maintain the hydration process or the cement/concrete will not harden properly.

Polymers reduce the rate of water evaporation, allowing the crystal structure to keep growing and building strength during these critical early curing stages. This reduced water evaporation is especially important in thin applications, where the surface area for evaporation is high, relative to the volume of the mortar.

2. Improved workability. Polymer modification noticeably improves application characteristics, making the mortar more fluid and easier to handle and apply. Certain polymers also prolong the hydration period, which can increase working time, an important characteristic in hot climates. This means contractors can use less water for workability purposes. The polymer acts as a water reducer, ultimately leading to a stronger mortar with fewer voids, or weak spots.

3. Improved adhesion. Polymer modifiers act as an adhesive to enable the modified mortar overlay to stick to a variety of surfaces such as concrete, masonry, brick, wood, rigid polystyrene and polyurethane foam, glass, and metals. Adhesion is an important property, especially in thin section overlay mortar applications such as spray coatings, stuccos, and underlayments, and applications with excessive vibration and heavy traffic.

4. Improved strength and durability. Cured polymer-modified mortars generally have improved tensile strength, flexural strength, impact and abrasion resistance, water resistance, and chemical resistance versus unmodified mortars. Also, the polymer in the mortar helps restrain micro-crack propagation, which improves the overall toughness of the mortar.

Applications

The combination of improved workability, adhesion, and curing performance allows using polymer-modified mortar in several niche applications that would otherwise be difficult or impossible. One thing most of these applications have in common is a thin layer of mortar, usually no more than 1 or 2 inches thick. All of them require one or more of the chemical and/or mechanical properties mentioned earlier.

Adhesives and Grouts:
 Wall and floor tiles—ceramic, marble, stone, etc. Adhesion, water/chemical resistance, flexural strength. This is the most common application for polymer-modified mortars.

Patch and Repair Mortars: Grouts for repairing cracks and delamination of concrete structures such as sidewalks, driveways, and walls. Adhesion, abrasion resistance, tensile and flexural strength. New mortar will not stick well to old concrete without polymer modification.

Waterproofing: Basements, bulk water storage tanks, septic tanks, ship decks, roof decks, and concrete walls. Water resistance for all; chemical resistance, other properties depending on the application.

Anti Carbonation Coating

Anti Carbonation Coating

A major factor in concrete decay is carbonation, caused by Carbon Dioxide (CO2) in the atmosphere reducing the alkalinity of concrete. This in turn results in reinforcing steel becoming susceptible to attack by water and oxygen, causing corrosion of the steel and eventually spalling of the concrete. Sulphates from vehicle exhausts and chlorides from de-icing salts also contribute to concrete degradation. Carbon Dioxide in the atmosphere reduces the alkalinity of concrete. The alkalinity of concrete is typically between pH12 and pH13, at these levels the highly alkaline nature of the concrete results in the formation of a passivation layer on the reinforcing bars, preventing corrosion. A drop in the level of alkalinity to a pH of below 9.5 eliminates the passivation and protection, making the concrete susceptible to attack by water and oxygen, leading to corrosion of reinforcing steel and eventually spalling of the concrete. Causes of decay in concrete:  weathering leading to erosion,  water absorption leading to rusting of reinforcement ,  insufficient concrete depth – corrosion of reinforcements, de-icing salts – chloride corrosion 

1. Carbonation depth amounts to only a few millimetres and cannot extend as far as the reinforcement. Carbonation protection (CO2-proofing) is not necessary. Where concrete quality is good and it is protected from the causes of concrete decay, carbonation is slight and eventually comes to a stop, with the depth reached being known as the maximum carbonation depth. 2. Carbonation has nearly reached the reinforcement layer. Carbonation protection is necessary in order to stop further progress. If carbonation penetrates deeper and reaches the reinforcement, the protection of the passivation layer around the rebar will be eliminated. If carbonation is stopped, the protection of the passivation layer will be retained and further decay of the concrete stopped. 3. The majority of the reinforcement is located in the already carbonated zone of the concrete. In this case, carbonation protection would be too late. The primary goal of surface protection is to protect the reinforcement from corrosion. If the concrete has already undergone carbonation, corrosion can only be prevented by waterproofing.

Superplasticizer Admixture for Concrete

Superplasticizer Admixture for Concrete

Superplasticizers, also known as high range water reducers, are chemical admixtures used where well-dispersed particle suspension is required. These polymers are used as dispersants to avoid particle aggregation(gravel,coarse and fine sands), and to improve the flow characteristics (rheology) of suspensions such as in concrete applications. Their addition to concrete or mortar allows the reduction of the water to cement ratio, not affecting the workability of the mixture, and enables the production of self-consolidating concrete and high performance concrete. This effect drastically improves the performance of the hardening fresh paste. The strength of concrete increases when the water to cement ration decreases

Sulfonated Napthalene Formaldehyde superplasticizers, the new generation of this kind of admixtures is replaced polycarboxylate ether-based superplasticizers (PCEs). With a relatively low dosage (0.15–0.3% by cement weight) they allow a water reduction up to 40%, due to their chemical structure which enables good particle dispersion.

RDP Redispersible Powder

RDP Redispersible Powder

Redispersible polymer powders are organic polymer powders obtained through the spray-drying of  aqueous emulsions. In combination with cellulose ethers and other additives. They help improve the properties and performance of cement- or gypsum based dry-mix products. Redispersible latex powders combine the performance benefits of liquid latex modifiers with the convenience, reliability and handling/storage advantages of one-component dry-mix systems.

Advantages  for end-use products include:
 
• Better water retention and open time• Better strength development of the mortar• Improved workability• Increased adhesion to a variety of substrates• Improved wetting of the substrate• Higher flexural strength and flexibility• Increased impact and abrasion resistance• Freeze/thaw resistance• Higher and more durable product quality (contributing to reduced job-site failure)

Process and Chemistry
The redispersible latex powder development process involves three key steps:1. Polymerization of dispersions that are specifically designed for redispersible powder production provides optimal application properties
2. Selection of appropriate protective colloid system to be added to liquid dispersion prior to the spray-drying process – provides optimal redispersibility
3. Selection of appropriate quantity and quality of anti-caking agents to be added during spray-drying provides optimal storage stability
Particle size distribution of the redispersion is a measure of the redispersibility – and is one of the most important  properties of a redispersible polymer powder. Smaller-diameter powder particles will contribute to more uniform redispersions with less clumping than larger-diameter particles.
