BOND FORCE ITA

PURPOSE

Bond Force ITA has been formulated to bond new concrete to old concrete and to improve the flexural strength of new concrete. It is especially beneficial in eliminating cracking (crazing), shrinking and minimizing bug holes in architectural, ornamental and other precast products. This recently improved version provides more than 18% greater strength than Acrylbond and competing products.

OTHER BENEFITS

Bond Force ITA can be added to the mortar mix for patching or re-surfacing concrete floors, pipe, box culverts or other precast products, driveways, terrazzo floors and masonry. It can also be used as a mortar admixture for setting stronger, more flexible tile floors and in making glass fiber reinforced concrete (GFRC). Bond Force ITA provides the following additional benefits:

For patching pipe or box culverts, Bond Force ITA provides a more secure, stable patch and will substantially reduce rejects.

For patching mortar, Bond Force ITA provides a greater shear, flexural impact and tensile strength resulting in a more durable finished product.

Bond Force ITA treated floors will last longer under heavy wear conditions or high vibration and have better abrasive strength, reduced dusting and a lower maintenance cost.

Bond Force ITA patches have excellent freeze/thaw resistance.

In making GFRC and architectural, ornamental and other precast concrete, the use of Bond Force ITA will result in a product with no shrinkage or cracking, significantly lower water absorption and porosity, increased abrasion resistance and increased aged strain to failure. In addition, Bond Force ITA will improve the workability of the mix and allow simple dry air curing.

LABORATORY TEST RESULTS

Test results using Bond Force only on a mix of 35% cement, 65% light weight aggregate, all to the same slump and a 5-day cure were as follows:

Additive	Treat Rate Oz / 100 lbs	Average Strength Psi	Water Absorption
No Additive	0	4200	13.0%
Acrylbond	100	4300	6.5%
Bond Force ITA	100	5100	6.0%
Bond Force ITA	300	6200	3.0%

Test results using Bond Force ITA and Ratio Master HVW on a mix of 28% cement, 72% 40 mesh sand, all to the same slump were as follows:

Additive	Treat Rate Oz / 100 lbs	Days of Cure	Average Strength Psi	Water Absorption
No Additive	0	1	2,274	7.7%
No Additive	0	28	3,976	7.5%
Ratio Master HVW	10	1	3,416	2.1%
Bond Force ITA	150
Ratio Master HVW	10	28	5,119	1.9%
Bond Force ITA	150

APPLICATION

For Eliminating Cracking (Crazing) and Shrinking in Precast Products:
For most applications, Bond Force ITA should be added at the rate of 100 to 200 ounces per 100 lbs. (6500 to 13,000 ml per 100 kg) of cement. If the aggregate is porous or the cement ratio is low, then more Bond Force ITA will be required. Bond Force ITA is compatible with most other additives; however, if you intend to use other admixtures, please contact us at the number listed below for consultation.

For Use as an Admix When Patching Mortar:
Pre-mix the sand and cement. Mix equal parts of water and Bond Force ITA in a separate container. Add the diluted Bond Force ITA blend and mix for 2-4 minutes. Continue adding the diluted blend until you obtain the desired slump and consistency; then apply the modified mortar over the bonding surfaces as a topping and feather the edge at least one inch.

If the mix is too wet, reduce the amount of water to stiffen. If the mix is too dry, increase the amount of Bond Force ITA and water. The water and Bond Force ITA solution should be added to the mixer prior to agitation; then add the sand and cement and mix thoroughly.

STORAGE AND AGITATION

Store this product in areas where the temperature exceeds 45oF and protect from freezing. Occasional agitation is required when stored for a period exceeding 30 days.
