“…The contribution of varying waste plastic contents on 28 days splitting tensile strength are -0.38, 0.25, 4.02 and 9.55% for 0, 0.25, 0.50, 0.75 and 1.00% waste plastic content respectively. This trend is similar to that reported by Suji et al [18], Hsie et al [19] and Nili & Afroughsabet [20], on splitting tensile strength of plastic fi bre reinforced concrete in which concrete containing plastic fi bres had higher splitting tensile strength than those of reference concrete, when the concrete has a comparatively low fi bre content (less than 1%) [21][22][23][24]. to be deterioration in the permeability properties of concrete, which according to Gu and Ozbakkaloglu [2], is attributed to plastic and natural aggregates not mixing suffi ciently in the concrete matrix.…”

This research focused on the integration of waste plastic into concrete in a bid to restrain water ingress when exposed to water. Polyethylene water sachet (PWS) was the source of waste plastic used. Waste plastic concrete treatments were designed and cast successfully with percentage waste plastic contents of 0, 0.25, 0.50, 0.75 and 1.00. It also involved a constant water/cement ratio of 0.45, a mix design of 1:2:4 and 2% by 342.85kg cement weight of superplasticizer. Twenty cubes, 20 beams and 45 cylindrical specimens were cast for compressive, fl exural, split tensile and water absorption tests respectively at 28 days of curing. Waste plastic treatments of 0.5% and 0.75% contents had the highest compressive strength. Water absorption characteristics of waste plastic concrete dropped with increasing plastic waste content to 0.75% after which further increase gave undesirable effects. Optimum water absorption (impermeability) were observed between 0.50% and 0.75% waste plastic content. Waste plastic concrete of 0.75% content with compressive strength and water absorption values of 21.19MPa and 0.22% respectively met the requirements of ASTM C55-11, ASTM C139-11 and CP 102. Waste plastic concrete showed desirable characteristics for potential use in the built environment.

“…Polypropylene fibers have been introduced into concrete to overcome the weakness in tensile strength [1][2][3] , improve the ductility and enhance the post elastic behavior and toughness [4][5][6] .For a long time, most measurements of static methods have yielded data on basic properties such as compressive strength, modulus of rupture and tensile strength. However, for many civil engineering concrete structures, such as water canal, bridges, pavement and offshore structures, which are normally subjected to repetitive fatigue load, the static mechanical data are not enough to predict the fatigue life for a given concrete structure, especially dynamic mechanic properties can not be described based on the static testing.…”

Properties and mechanism were investigated on flexural fatigue of concrete containing polypropylene fibers and ground granulated blast furnace slag(GGBFS). Four polypropylene fibers' volume fractions and fi ve slag proportions were considered. An experiment was conducted to obtain the fatigue lives at three stress levels in 20 Hz frequency and at a constant stress level of 0.59 in four frequency respectively. Mechanism and evaluation were investigated based on the experimental data. Fatigue life span models were established. The results show that the addition of polypropylene fi bers improves the fl exural fatigue cumulative strength and fatigue life span. It is proposed that the slag particles and hydrated products improve Interfacial Transition Zone (ITZ) structure and benefit flexural fatigue performance. A composite reinforce effect is found with the incorporation of slag and polypropylene fi bers. The optimum mixture contents 55% slag with 0.6% polypropylene fi ber for the cumulative fatigue stress. Fatigue properties are decreased as the stress level increasing, the higher frequency reduces the fatigue strength more than lower frequency at a constant stress level.

A b s t r a c t This research work mainly focuses on improving the concrete strength based on fiber reinforcement both in compression and tension. Concrete with various mix proportions containing dosage of Polypropylene (PP) fiber of lengths ranging from 13 to 25 mm with coarse aggregate replacement levels at 10%, 20%, and 30% by dismantled road aggregate were made and the compressive and tensile strengths were investigated. The experimental test results revealed high compressive and tensile strength at curing period of 28 and 56 days. The specimens tested observed that due to addition of fiber, the fibers could hold the matrix together even after extensive cracking and crushing. Net result of all these is to impart to the fiber composite pronounced post-cracking ductility which is absent in traditional concrete. In order to provide base for comparison, concrete specimens as a reference were cast without the addition of polypropylene fiber. Test result revealed that by adding polypropylene fibers at 6grams per one kg of cement a considerable improvement in the strength of concrete of 37.68 MPa and 43.59 MPa at 28 and 56 days respectively with 10% coarse aggregate replacement by recycled aggregate is achieved.
