Fibrous concrete is one of the most usable materials in construction industry. There are several different fibroses that are used in concrete including Polypropylene fibrous. Recently polypropylene fibrous concrete are used vastly in constructions such as road pavement, airstrip, massive foundations with big deflections, and especially in concrete cover of tunnels. The most noticeable defects of fibrous concrete is high porosity that shows negative effects on mechanical properties of concrete. The pores in these type concretes are considered one of the most intensifying weakness factor in durability and integrity. In this regard, scientists suggest various solutions to reduce these pores in concrete such as use of pozzolanic cement, use of silica fume to replace part of the cement, utilization of special kind of microorganism in cement paste, etc. Among the solutions presented that have environmental benefits is use of calcium carbonate deposition of bacterial properties and permeability of polypropylene fibrous concrete.In the event of achieve the study goals, samples are divided in two main groups: samples that have bacteria in concrete mixing water and samples intubated. Impact tests by a specific bacterium Bacillus bacteria called Bacillus Pasteurii families by different experiments were performed on the samples. In the first group of samples, the concentration 1× Cells / ml of bacteria is added to the concrete mixure at the time of mixing concrete; While in the second group of samples, flexible tubes at the time of making concrete, mold and embedded in concrete mixture and then poured on them, In other words these samples containing tubes are built-in. In these samples, the concentration of 1× Cells / ml on a weekly basis for four weeks to be injection tube. In both cases,there are four mix designs with different percentages of polypropylene fiber volume: 1-Samples without fibers (0% fiber), 2-Samples containing 0.4% fiber, 3- Samples containing 0.6% fiber, 4- Samples containing 0.8% fiber. It should be noted that all design mixes were designed and built with 12 and 19 mm fiber length. Generally,42 cube samples for water absorption test at 70mm dimensions,84 cube samples at 100mm dimensions for compressive strength test between the ages of 7 and 28 days, 42 prismatic samples by dimensions of 200×200×120 mm for the test of concrete permeability and 63 prismatic samples by the dimensions of 100×100×350 mm for bending and patience test were made. By analyzing the results and comparing them can be say that using Bacillus Pasteurii bacteria in polypropylene fiber reinforced concrete improved mechanical properties and durability of concrete. So that the compressive strength of concrete at 28 days at most 30%, water absorption nearly 40%, concrete permeability about 20% and the bending strength of concrete about 30% improved. By comparing the results of samples containing bacteria in water with samples were intubated, it can be concluded that the samples containing bacterial suspension have better performance in the mechanical properties of the samples have been intubated. Although both samples have a significant improvement compared to the control samples, but it also seems necessary to note when cannulation method using bacteria have fewer restrictions applicable compared with the samples that use of bacteria in the water mixing concrete.
