English Abstract
The usage of high strength glass fiber reinforced concrete (HSGFRC) in the construction applications has been increasing worldwide and will make an impact in Gaza Strip.
Due to the limited land area available for construction, the fast growing population, bad and unstable political conditions, and the continuing wars in Gaza Strip, strong, relatively cheap, and locally available repairing and strengthening material should be produced.
The main objective of this investigation is to study the effect of addition of alkali resistant glass fiber reinforced polymer (AR-GFRP) with various proportions typically 0.3, 0.6, 0.9, and 1.2 by weight of cement on the mechanical behavior of plain HSC (without fiber) with 28 days cube compressive strength up to 60 MPa using available materials in the Gaza local market.
Results show that it is possible to produce HSGFRC in Gaza strip using materials that are available at the local markets if they are carefully selected.
Based on the experimental results, the compressive strength, splitting tensile strength, flexural strength and density of HSC is found to be increases as fiber percentage increases for both ages 7 and 28 days.
The compressive strength of HSC is found to be 57.85, 61.05, 66.01, 66.34 and 66.60 MPa at fiber percentage of 0.0, 0.3, 0.6, 0.9, and 1.2 respectively for 28 days.
The 28 days percentage of increasing over the reference mix is found to be maximum equal to 13.14 percent at 1.2 fiber percentage.
The density of HSC is found to be increases very slightly as fiber percentage increases from 0.0 to 1.2, typically from 2417 to 2441 kg/m3.
The splitting tensile strength of HSC is found to be 4.12, 4.77, 5.53, 5.84 and 6.73 MPa at fiber percentage of 0.0, 0.3, 0.6, 0.9, and 1.2 respectively for 28 days.
The 28 days’ percentage of increasing over the reference mix is found to be maximum equal to 63.22 percent at 1.2 fiber percentage.
The flexural strength of HSC is found to be 6.35, 7.53, 8.28, 8.79 and 9.68 MPa at fiber percentage of 0.0, 0.3, 0.6, 0.9, and 1.2 respectively for 28 days.
The 28 days’ percentage of increasing over the reference mix is found to be maximum equal to 52.36 percent at 1.2 fiber percentage.
The mode of failure is found to be taken place gradually with the formation of cracks as fiber percentage increase, compared with plain HSC specimens, the failure was sudden and completely destruction.
Hence it is established that the presence of fibers in the matrix has contributed towards prevent sudden crack formation.
