There are several problems generated by the construction of roads and lack of support on surfaces where pressure is generated, generating landslides, for this purpose solid structures with slopes are sought to resist the weight and pressure, which is generated, for which the present investigation had as main objective to study the influence of the incorporation of SIKA FIBER FORCE PP48 and SIKA FIBER CHO 6535 NB, in the mechanical properties of conventional mortar, being the case of the resistance to bending, in three points and the proportion that was used, for this investigation was 1 of cement: 2 of sand with a water / cement ratio of 0.50. In the elaboration of the test pieces, for this investigation the Cement Pacasmayo Portland Type I was used, drinking water of the city of Trujillo and the fine sand brought from the quarry "San Idelfonso", located within the province of Trujillo; various sand tests were performed such as: granulometric analysis (ASTM C136), moisture content (ASTM 566), specific gravity, absorption (ASTM C128) and loose and compacted unit weight (ASTM C29), as well as physical quality- Chemistry (ASTM D4972). For the forming of specimens, it was reinforced with fibers, in different additions 20,40,60,80 and 100 g, for SIKA FIBER CHO 6535 NB Y 5.10 and 15 grams for SIKA FIBER FORCE PP48; the mortar bending resistance test was carried out, for which the ASTM C293 standard was used, where the test pieces used were of dimensions 16 cm x 4 cm x 4 cm, cured in water and tested at an age of 28 days, according to NTP 399.602. With the execution of this investigation, it was concluded that the mortars for slopes, reinforced with SIKA FIBER CHO 6535 NB, reached higher values than those reinforced with SIKA FIBER FORCE PP48, reaching a value of up to 262.4 Kg / cm2, when reinforced with 100 grams of said fiber, compared to mortars reinforced with polymeric fiber, reaching maximum values of 162.4 Kg / cm2, determining that in mortar for slopes, regardless of the addition of fiber, SIKA FIBER CHO 6535 NB, this is the best component used as reinforcement, in mortar for slopes. Inclusive the cost, for the elaboration of the mortars for slopes, is economically accessible, since the price of SIKA FIBER FORCE PP48, is of S / .138, in a packaging of 5 kg., And of SIKA FIBER CHO 6535 NB, is of S / .203.70, but in a pack of 20 Kg., for which regardless of the amount of mortar to be processed, the addition of metal fibers is much cheaper, because in an equivalent to 5 Kg, the price would be S /.50.90.
