English Abstract
The main objective of this research is to study the effect of several nano mineral materials (NM) on the mechanical properties of concrete in order to produce high strength concrete of about 50 MPa with good workability.
The NM materials used in the research were not heavily used in the production of concrete.
Normal concrete was applied to study the effect of the NM materials on the mechanical fresh and hardened properties.
The applied NM materials in research were brown iron oxide (BIO), yellow iron oxide (YIO), Titanium dioxide (TiO), Barium sulfate (BaS), Kaolin (CCK) and acid poly acrylic (PAA).
These materials are considered as filler materials.
This means that they do not generally react with concrete components.
The mechanical properties of fresh and hardened concrete have been studied for normal strength concrete without any NM and with 6 NM materials.
Five contents were applied for each NM materials.
These ratios were ranging from 0.5% to 2.5% of BIO and BaS and range from 1% to 5% of YIO, TiO, PAA and CCK.
Also, the current research studied the case of considering PAA as a main gradient and adding each of the remaining five NM materials individually, in order to improve workability.
The slump tests, compressive strength tests were conducted for all specimens with and without NM materials.
The indirect tensile strength, flexure strength, shear strength and modulus of elasticity were carried out for concrete specimens having 2.5% BIO and those with concrete specimens having 2.5% BIO with 5% of PAA.
The results showed that PAA improves the workability of fresh concrete also can be used BIO, YIO, TiO and BaS to improving the mechanical properties of the hardened concrete with varying degrees.
The results also indicated that using 2.5% of BIO by cement weight enhances the compressive strength of hardened concrete from 37.37 MPa to up to 50 MPa and the workability improved from 90 to 105 mm.
The results also revealed that using 5% of BIO by cement weight and 2.5% of PAA enhances the compressive strength from 37.37 MPa to up to 49.35 MPa and workability of fresh concrete about from 90 to 170 mm
