"Anti-Hydro"® Cold Weather Concrete: A Concrete Admixture That Has Been Widely Used Since 1904 In Cold Weather Conditions, Often Eliminating The Need For Externally Applied Heat. Waterproofs And Increases Strength, Workability, Hardness, And Durability.

Since 1904, we have been cooperating with many types of contractors and engineers in placing concrete under adverse temperature conditions. "Anti-Hydro" has been used successfully in thousands of jobs as one of the measures to protect concrete from damage, often eliminating the need for externally applied heat.

"Anti-Hydro" is a combination of non-chloride organic and inorganic chemicals that react with portland cement to produce more complete hydration. Water requirements, bleed water, segregation and shrinkage are reduced. The increased hydration provides internal curing and a much denser cement paste. These combined reactions produce impermeable concrete that is hard and non-dusting. 

We quote from recommended practices for cold weather concrete ACI (306-66), Chapter 1: "The primary objective in cold weather concreting practices is to establish a procedure that will assure, despite freezing weather, that the concrete be amply strong and durable to meet fully its service requirements. The duration of protection required to develop strength will vary with the likelihood of conditions being favorable to continuing strength development immediately after protection. Also, it will vary with the strength that is needed immediately thereafter for structural safety. Usually the protection to assure sufficient strength will be appreciably more than will be needed to assure good resistance to weathering."

This concurs with our experience that concrete that has obtained substantial compressive strength will not be adversely affected by a few freeze-thaw cycles. There are of course, a great number of variables that affect the development of concrete strengths. "Anti-Hydro" is extremely helpful in the development of initial set and high early strengths at low temperatures. "Anti-Hydro" reduces the water requirements and reacts with portland cement to permit more complete hydration. The increased hydration utilizes more of the mixing water and liberates additional heat of hydration over a shorter time. This additional heat develops early initial set and high early and ultimate strengths, particularly if heat loss is minimized by the mass of the concrete and form insulation.

Concrete may be safely placed in cold weather if necessary preparations are made, proper mixes are designed and correct placing, finishing, and curing techniques are followed. (Call us at 1-800-777-1773 for further advise on how to use our products.) The mass and exposure of concrete being placed should be considered in determining cold weather concreting procedures.

A-H Polysealant "T": A Polysulfide Based (on Thiokol®) Joint Sealant That Has Been Extensively Used To Effectively Seals All Joints, Moving And Non-moving, Against Water And Dirt.

A-H Polysealant "T" is a two component, polysulfide based (on Thiokol®) sealant which effectively seals all joints subject to structural movement as well as non-moving joints against infiltration of water and dirt. It is available in Pour Grade (Self Leveling) and Gun Grade (Non Sag) versions.

A-H Polysealant "T" is used for sealing reservoirs, dams, canals, culverts, flood control channels, as well as joints subject to exposure in waste water treatment. Also used for sealing curtain-wall panels, tilt-up panels, window glazing, flashing and metal setting. Also, for all joint-seal applications where a short curing period is required, such as expansion and contraction joints in shopping centers, sidewalks, or other traffic areas.

A-H Polysealant "T" will effectively prevent water from entering the sealed joints and thereby eliminate erosion of the soil underneath the slabs. Particularly areas which are watered frequently, such as swimming pool decks and around planters must be protected. All coping joints and deck joints should be sealed. In adobe soil areas, unsealed joints may cause swelling of the soil and subsequent buckling and cracking of the concrete slab. It maintains a low modulus of extension even after prolonged exposure to the elements. This prevents adhesive and cohesive failures which often occur when a caulking compound hardens excessively with aging.

A-H Retard Set: A VOC Compliant, Liquid Applied, Concrete Surface Set Retarder That Has Been Extensively Used For Exposing Concrete Surface Aggregates.

A-H Retard Set is a VOC compliant, non-flammable, non-toxic, liquid applied, concrete surface set retarder. It is mainly used on concrete surfaces to produce an exposed aggregate effects or a rough surface for bonding subsequent applications. A-H Retard Set is applied as a coating to freshly placed concrete surfaces. It chemically delays the setting of the concrete surface and allows for the removal of the surface mortar at a later time, thus exposing surface aggregates for decorative, rough or non-slip effects. A-H Retard Set permits uniform reveal to a depth of up to approximately 1/4" (depending upon conditions). The setting of the concrete below the retarded slab surface is not affected.

A-H Retard Set is recommended for sidewalks, ramps, wall, patio, pool aprons, pre-cast slabs or wherever decorative rough textured, non-slip surface effects are required.
