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 SP-311

DESCRIPTION

ConTec SP-311 is a ready to use liquid plasticizing and swipe producing admixture for use in low slump concrete masonry units. It’s unique multi-component chemistry creates a moderate to high swipe appearance and minimizes both feed and compaction times with its lubricating properties. SP-311 improves compaction and density producing higher compressive strength and a less permeable surface.

APPLICATION

Use ConTec SP-311 in all types of manufactured concrete where moderate to high swipe is desired

PACKAGING

ConTec SP-311 is available in bulk quantities or packaged in 55 gallon (208 L) drums weighing 490 lbs (222 kg) and 260 gallon (984 L) totes weighing 2390 lbs (1084 kg).

TYPICAL PROPERTIES

Specific Gravity at 77F…….…… ….. 1.01
Viscosity at 77F, cps ……….…. 50 – 100
Weight per gallon ……………… … ….….. 8.4
% Volatile matter (NVM(1)) ……… 86 – 88

FEATURES / BENEFITS

● Produces a moderate to high swipe.
● Creates more defined edges improving overall appearance.
● Optimizes material flow which shortens overall machine cycle times.
● Increases compressive and flexural strength.
● Added components improve cement particle dispersion and hydration.
● Reduces mechanical abrasion in equipment.

HANDLING / STORAGE

ConTec SP-311 should be stored at temperatures above 35°F (2°C) Care should be taken to prevent this product from freezing. Should SP-311 freeze, warm till completely liquid then use mechanical agitation to reconstitute.

ADDITION RATES

The recommended dosage is 2 – 5 fl oz /100 lbs (130-325 mL/100kg) of cement. As with most plasticizers, water content should be monitored to achieve desired appearance. SP-311 is not a water reducer and should not be utilized as such. 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 SP-311 with other admixtures before application.

ConTec SP-307

DESCRIPTION

ConTec SP-307 combines a swipe agent with an effective mix lubricant and hydration aid. It’s unique chemistry creates a low to moderate swipe appearance while its lubrication properties minimize both feed and compaction times. SP-307 is ready to use liquid for use all low slump concrete masonry units. SP-307 improves compaction and density producing higher compressive strength and a less permeable units.

APPLICATION

Use ConTec SP-307 in all types of manufactured concrete where low to moderate swipe is desired. SP-307 is not a water reducer and should not be utilized as such.

PACKAGING

ConTec SP-307 is available in bulk quantities or packaged in 55 gallon (208 L) drums weighing 490 lbs (222 kg) and 260 gallon (984 L) totes weighing 2390 lbs (1084 kg).

TYPICAL PROPERTIES

Specific Gravity at 77F…….…… ….. 1.02- 1.04
Viscosity at 77F, cps …………..… .…. 75—150
Weight per gallon ………………… ….….. 8.6
% Volatile matter (NVM(1)) … ……… 12—17

FEATURES / BENEFITS

● Improves cement particle dispersion and hydration.
● Produces a low to moderate swipe.
● Increases compressive through better compaction and hydration.
● Optimizes material flow which shortens overall machine cycle times.
● Creates more defined edges improving overall appearance.
● Reduces mechanical abrasion in equipment

HANDLING / STORAGE

ConTec SP-307 should be stored at temperatures above 35°F (2°C) Care should be taken to prevent this product from freezing. Should SP-307 freeze, warm till completely liquid then use mechanical agitation to reconstitute.
