ConTec NC-537P

DESCRIPTION

ConTec NC-537P is a non-corroding, chloride free accelerator/plasticizer blend. It does not corrode metal block and paver pallets or machine parts. It promotes early strength development and ease of manufacturing in concrete masonry unit (CMU) mix designs. NC-537P helps offset the effects of cold weather by increasing hydration speed. It should be used year-round to shorten time between CMU manufacture and splitting or tumbling.

APPLICATION

ConTec NC-537P is compatible in all CMU mixes. It may be added to the mix on the sand or in the water.

PACKAGING

ConTec NC-537P is available in bulk quantities or packaged in 55 gallon (208 L) drums weighing 560 lbs (254 kg) and 265 gallon (1003 L) totes weighing 2750 lbs (1247 kg).

TYPICAL PROPERTIES

Specific Gravity at 77F…….…… ….. 1.17 – 1.18
Viscosity at 77F, cps …………..… .…. 50—100
Weight per gallon ………………… ….….. 9.8
% Volatile matter (NVM(1)) ………… …… NA

FEATURES / BENEFITS

● Compatible with all types of Portland cement.
● Ideal in masonry units that will be split or tumbled shortly after manufacturing.
● Increases the early strength of a concrete mixture.
● Plasticizer component adds lubricity to mix.
● Consolidates accelerating and plasticizing admixes into one economical product.
● Easily dispensed with conventional admix dispensers.

HANDLING / STORAGE

ConTec NC-537P will freeze at approximately 23°F (-5°C), but can be completely restored by thawing and thorough agitation. It may cause irritation to eyes and skin upon contact. Proper protection should be worn.

ADDITION RATES

Dosage must be determined by in-plant testing and is usually in the range of 8 to 30 US fluid ounces per 100 pounds of cement. Your ICT sales representative will help you determine your exact dosage.

ConTec NC-505

DESCRIPTION

ConTec NC-505 is a non-corroding, chloride free accelerator. It does not corrode reinforcing steel or pre-stressed strands in concrete. It promotes strength development of the concrete and meets ASTM C 494 requirements as a type C admixture. NC-505 offsets the effects of cold weather by increasing hydration speed.

APPLICATION

ConTec NC-505 is compatible in concrete with all commercial air entraining admixtures. The amount used will depend upon the setting time of the non-admixture concrete and the temperature at placement. It may be added to the mix on the sand or in the water.

PACKAGING

ConTec AC-505 is available in 55 gallon (208 L) drums weighing 620 lbs (281 kg) and 275 gallon (1041 L) totes weighing 3150 lbs (1429 kg).

TYPICAL PROPERTIES

Specific Gravity at 77F……..…… ….. 1.30 – 1.32
Viscosity at 77F, cps ……….…..… .…. 50—100
Weight per gallon ………………. ….….. 10.90
% Volatile matter (NVM(1)) …………. …… NA

FEATURES / BENEFITS

● Compatible with all types of Portland cement.
● Offers a significant reduction in corrosion to steel reinforcing.
● Increases the early strength of a concrete mixture.
● Designed for use in cold weather concreting.
● Shortens setting time for concrete.
● Easily dispensed with conventional admix dispensers.

HANDLING / STORAGE

ConTec NC-505 will freeze at approximately -15°C, but can be completely restored by thawing and thorough agitation. It may cause irritation to eyes and skin upon contact. Proper protection should be worn.

ADDITION RATES

The dosage range is 0.5 – 2.6 liters per 100Kg of cement. NC-505 at 0.78 – 0.98 liter per 100Kg of cement will reduce the setting time of typical Type I cement concrete by 2-3 hours (at 10°C) and a 25 to 50% increase in 3 day compressive strength is normally achieved.

ConTec AC-501

DESCRIPTION

ConTec AC-501 is a ready to use liquid admixture formulated to provide set acceleration and .increased early strength development in concrete. AC-501 is comprised of Calcium Chloride with additional chemical enhancements, to improve its effectiveness.

APPLICATION

Use ConTec AC-501 in all zero-slump applications including gray block, architectural block, segmental retaining wall, pavers, roof tile, and slabs. AC-501 improves cement hydration may change the demand for batch water. For maximum product improvement always add batch water at the maximum allowed rate with your process.

PACKAGING

ConTec AC-501 is available in 55 gallon (208 L) drums weighing 620 lbs (281 kg) and 275 gallon (1041 L) totes weighing 3150 lbs (1429 kg).

TYPICAL PROPERTIES

Specific Gravity at 77F…….………..1.31 – 1.32
Viscosity at 77F, cps ……………….………<50
Weight per gallon ……………………….. 10.90
% Volatile matter (NVM(1)) ………………N/A

FEATURES / BENEFITS

● Increases product early and final strength.
● Offsets the effect of low temperature on setting time and early strength.
● Shortens setting time and increases rate of strength development.
● Designed for use in cold weather concreteing.
● Cement hydration increases and helps raise and maintain temperature.

HANDLING / STORAGE

ConTec AC-501 can freeze at extremely low
temperatures, but can be restored by thawing and
thorough agitation. Always use cold water when
diluting calcium chloride solution. Leather clothing and shoes will be damaged by calcium chloride.

ADDITION RATES

The Dosage range for AC-501 is 7 to 18 US fl. Oz./100 lb. of cement. 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 AC-501 with other admixtures before application. Flush dispensing equipment before changing to or from any another admix.
