Abstract

The present research aims to describe and explain the placement of the collaborating plates, the dosage and the cracking in the collaborating slabs and how Fibromac12 provides resistance in the concrete of the slabs in the parking lot of a shopping center in Miraflores-Lima. The procedure for the investigation considered the review of bibliographic material, manuals and quality protocols to determine the application of the collaborating plates on the existing structure and the behavior of the concrete resistance of the slabs due to Fibromac12, considering the activity of use of the downtown parking. The results found show that the placement of the plates presents three typical supports A, B and C defined in the construction manual; Regarding dosage and cracking, it was determined that Fibromac12 improved the quality of the concrete by 21%, finally the cracks were classified according to their thickness and pattern, which allowed us to determine the cracking patterns. The conclusions establish that the collaborating plates need to be placed with a minimum support of 12 mm for type A and 40 mm for type B support. The concrete dosage incorporating 71 grams of Fibromac12 per bag of cement increases the concrete quality at 28 days, improving on average 21% of its resistance and with respect to cracking, no plastic shrinkage cracking patterns were found, so Fibromac12 is controlling this type of cracking.
