SD-220C

DESCRIPTION

Contec SD-220C is the concentrated form of SD-220. It is approximately three times more powerful. After adjusting for activity or dilution it can be used in any application that calls for Contec SD-220. ConTec SD-220C is a dispersing aid featuring cutting-edge polycarboxylate technology. It’s highly effective formulation improves cement and color pigment efficiency in all types of architectural and hardscape concrete units. SD-220C improves cement hydration and provides higher compressive strength in manufactured concrete products. Your ICT technical representative can help you design a mix that will used SD-220C to actually reduce manufacturing cost.

TECHNOLOGY

Cement particles stick together in clumps called agglomerations. This clumping prevents water from reaching all the cement. Use of ConTec SD-220C admix breaks up agglomerations to increase the cement surface area available for hydration. The increased surface area holds more water without slumping your mix.  Maximizing the water content of zero-slump mixtures will maximize your results with SD-220C.

PACKAGING

ConTec SD-220C is available in bulk quantities or packaged in 55 gallon (208 L) drums weighing 485 lbs (220 kg) and 260 gallon (984 L) totes weighing 2425 lbs (1100 kg).

HANDLING / STORAGE

ConTec SD-220C should be stored at temperatures above 35°F (2°C) Care should be taken to prevent this product from freezing. Should SD-220C freeze, warm till completely liquid then use mechanical agitation to reconstitute

ADDITION RATES

The recommended dosage is 0.7 – 1.0 US Fluid Ounces per 100 weight of cement. In dry-cast concrete products SD-220C will increase the demand for water by 5% to 10% above normal addition rates. SD-220C is not a water reducer and should not be utilized as such. If you require a Super-plasticizer or water reducer see SD-215 or SD-215C. Please consult an ICT representative for further recommendations to determine the proper dosage rate and order of addition for your particular process. Order of addition procedures can vary per facility. Never mix SD-220C with other admixtures before application.

Paver Green Density – A Crystal Ball for QC

Green Density Rig

Typically the paver manufacturer makes units and sends them to the lab for testing. On the rare occasion that the lab finds they do not meet spec the pavers are already made in quantity, perhaps sold, perhaps installed. Pavers are so over built that this is almost never a problem. But wouldn’t it be so much better if the

Green Density Rig

Funny Looking Crystal Ball

producer could consult a crystal ball and see test results of his pavers as they were being made? With this mystical power the issue with the production could be addressed right on the spot. If only there was such a power to see the future.

But wait, there’s more! That ability is available to mere mortals. It is green density testing done right at the machine as the units are made.

You’ve seen the cured density on every test report. 142 pounds per cubic foot (PCF) and kick butt compressive strength. Or on a bad day 132 PCF and a nasty fail on compressive strength. (Example numbers only, it always varies) With green density measurements at the machine you can know in advance what your cured unit density will be with very good certainty.  You get to peer into the future.  Very cool.

The set up is simple,a lab scale, water, and a rig to weigh the green unit in air and submerged. You could put it in a circus tent and have a mysterious gypsy woman do the test but this crystal ball doesn’t require those trappings. Just the determination to be a professional, quality, producer.

We encourage our customers to ask for more info. If you are, Deity of Your Choice forbid, not our customer then let’s talk about our products and technical support.

Permeable Pavers are a type of Interlocking Concrete Paver.   They are designed to allow rain water to pass through the paver layer into a sub-base designed to handle the runoff.  The absorption of rain water and slowly dispersing it into the ground is much more natural than capturing it in a retention pond for disposal.  The land devoted to retention pond is either eliminated or greatly reduced.  More land is available for green space or development and rain water now naturally recharges the ground water.

Sealers

ICT offers acrylic polymer and silane/siloxane sealers.   Both these water-based sealers offer effective protection for your concrete surfaces and masonry units.

Use our acrylic based sealers increased gloss is desirable.  By varying the application rate of our acrylic sealers you can adjust the gloss from very slight to semi-gloss.

We suggest avoiding heavy application rates in areas with foot or vehicular traffic.  Over application results in a finish may be high-gloss but it will not be durable.

It is best to use thinner applications allow the sealer to soak in without puddling on the surface.  The protection is locked into the concrete, not laying exposed on the surface of the concrete.

Particle Dispersants

Super Dispersant

Particle Clumping is Reduced for Improved Hydration

ICT Particle Dispersants are used in both zero-slump and wet-cast mix designs.  The chemical action is the same in both applications but the dose and the physical results are very different between these two mixes.

In wet-cast ICT “SD” products act as water-reducers and super-plasticizers.   In zero-slump the same exact same products could be more accurately described as water-increasers.

These opposite seeming properties are both the result of ICT dispersant’s ability to modify and enhance how water interacts with the cement, pigment, and aggregate particles in concrete.  They are both improve the physical properties of their respective mixes.  Yes, it can be confusing.

ICT will help you match the most beneficial “SD” product to your concrete mix.

Air-Entraining Agents for Concrete

Image182Air-Entraining Agent, or “AEA”, is used in poured concrete to cause the incorporation of very tiny air bubbles.  These are bubbles increase the concrete’s resistance to degradation caused by freeze and thaw cycles.

AEA is not effective in zero-slump concrete such as is used in interlocking concrete pavers, architectural block, or segmental retaining wall.  These mixes have to little water to effectively form the tiny bubbles (“good air”).

ICT’s AEA is used by our precast customers to increase the durability of their product.

Efflorescenc Control Agents (Admix)

Hydrophobic Concrete

Hydrophobic Concrete

ICT has a full line of Efflorescence Control Agents, or ECA’s.

Efflorescence is a harmless, but unattractive, white deposit that can form on any concrete.  It is the result of a reaction between water-soluble compounds in the concrete and carbon dioxide in the atmosphere.  The water-soluble chemical is primarily calcium hydroxide, a normal left over from the hydration of cement.

The chemical reactions that dissolve and dissipate efflorescence are much slower than the reactions that me it in the first place. . If you were very very patient this “white bloom” will wash away in the rain.

ICT ECA’s help prevent or reduce the formation of efflorescence before it starts.  By controlling the movement of water through the concrete, the availability of the water-soluble compounds, and numerous other factors,  ICT ECA’s help to reduce and control efflorescence.

For more information call 908-453-2737 and ask for technical information or email info@bestadmix.com.
