Fritz-Pak Concrete Superplasticizer Additive, 2.4lbs. Cement Water Reducer Improves Workability And Strength. Plasticizer Gives 6 in Slump Increase. Great for DIY Countertops, Slabs, Patios And Floors
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (for its visual resemblance to Portland stone). Many other non-cementitious types of concreteexist with other methods of binding aggregate tog

This Bon product is actually a bag of Owens Corning Anti-Crak HD (High Dispersion). According to the Owens Corning product sheet, "These fibres are designed to be used with normal concrete mixes at very low addition levels – typically 0.6kg/m3 (1lb/yd3) of concrete.
Flowing concrete is a highly fluid but workable concrete that can be placed with little or no vibration or compaction. The effect of superplasticizers lasts only 30 to 60 minutes, depending on the brand and dosage rate, and is followed by a rapid loss in workability. As a result of the slump loss, superplasticizers are usually added to concrete ...

Jul 17, 2017 Fiber-reinforced concrete uses Fibermesh, a proprietary additive, to increase tensile strength limit or prevent cracking. Small particles of synthetic or steel fiber are blend into the concrete mixture. These fibers uniformly mix throughout the concrete and align in no particular direction.
Damp-proofing admixtures for concrete. These are additives used for watertight concrete, and their task is to reduce the capillary absorption of the concrete mix by blocking the capillary pores. Waterproofing admixtures make it possible to obtain concrete surfaces that are resistant to water and to aggressive chemical agents.
The additive act in three ways. Filler; Nucleating; Pozzolanic; 1. Filler: These additives/admixtures are finer than cement, so when added to concrete they occupy the small pores previously left vacant. 2. Nucleating: These fine particles accelerate the rate of hydration and precipitation starts. 3. Pozzolanic:

A The origin of these terms dates back to when most concrete recipes were three-part mixes: aggregates, portland cement, and water. Engineers, producers, and contractors considered any other ingredient added to the batch recipe to be an additive or admixture.
Antifreeze additives in concrete - allow to conduct construction procedures using concrete mixtures even at minus temperatures, withstand frosts to -15 degrees, and some up to -25 degrees. Additives for accelerated durability - are necessary to increase this figure for the first time day, and the strength of ready-mixed concrete also increases.

These additives are often used to ensure concrete quality is met when unideal conditions exist (i.e. cold weather) The majority of admixtures come in ready-to-use liquid form and are added to the concrete at the plant or at the jobsite. Some admixtures like pigments, expansive agents, and pumping aids are used only in extremely small amounts ...
Fly ash was used as cement replacement additive. The concrete mix was prepared in accordance with the requirements of standard EN 196-1:2016 . 7 batches of concrete mixes were mechanically produced under laboratory conditions for the tests.The batches differed by the type of cement and fly ash content ranging from 0% to 65% by weight of cement (the binder was replaced by silica fume).
Antifreeze Admixtures for Concrete. The antifreeze admixtures affect the physical condition of the mix water used in the concreting. These can depress the freezing point of the water to a large extent and can be used in temperatures lesser than -30 degrees Celsius.
In this lesson, you'll learn how to properly mix and pour concrete. Though mixing concrete might seem straightforward it's actually the easiest part to get wrong. In this short lesson we'll cover best practices for mixing and pouring concrete to achieve the best results, along with additives that can change the properties of your concrete mix.

Concrete admixtures are natural or manufactured chemicals or additives added during concrete mixing to enhance specific properties of the fresh or hardened concrete, such as workability, durability, or early and final strength.
Concrete admixtures (additives) enhances the properties of concrete for applications in construction with special requirements. Concrete additives are used to achieve desired workability in case of low water cement ratio, and to enhance setting time of concrete for long distance transportation of concrete.
