| Abstract | ||
| This study is amid to evaluate the use of Iraqi cement in high strength concrete (HSC) by production methods and investigation the mechanical properties such as compressive strength and splitting tensile strength. Four types of local made cement with one type of imported cement were used in concrete mixes. High strength concrete were produced using cement, crushed aggregate, fine aggregate and Superplasticizer. A comparison is made of mechanical properties of high strength concrete made with different types of cements. Experimental results showed that the higher compressive strength was gain at early ages of concrete mixes with imported cement while the compressive strength gain is lower at early ages of concrete mixes made with local made cement. Results showed that higher compressive strength gain at later ages of concrete mixes with local made cement till the compressive strength of these mixes reaches the compressive strength of concrete mix which contain imported cement at age of 90 days. Compressive strength of the investigated concreted were ranged between (61 – 91 ) MPa, (45-86) MPa, (42-87) MPa, (37-85)MPa , (32-82)MPa and splitting tensile strength were (5.75-6.85)MPa, (4.1-6.5)MPa, (3.8-6.3)MPa, (3.2-6.1)MPa, (2.65-5.2)MPa for concrete mixes made with AlQaseem cement (imported cement), Taslooga cement, AlMuthana cement, Kerbala cement, and Kufa cement (types of local made cement) respectively. | ||
