The Attributes of Concrete Produced by using of Aljufra and Sirte Aggregate
Ahmed Mohmed Ahmed Blash [3] | Hussein Mohmed Hussein Ahmeed [2]
Abstract: This study was to know some of the mechanical characteristics of the two types of aggregate at different rates used in the central region in Libya (the aggregate of the Sirte limestone, Ruins of volcanic Aljufra) impact on resisting pressure and concrete floats after testing available led the research results to the following conclusion Knowledge of the mechanical characteristics of the aggregate help in determining the validity of the use of the most suitable places for use and the results indicate that the aggregate of Aljufra is mechanical properties best in terms of the percentage of low absorption compared to the Sandbank Sirte containing the pores more than weaken its resistance to pressure the stretching, also Aljufra aggregate gave the highest results from shock hand land resistance is therefore more appropriately mixture prone to crash land concrete factories, warehouses and roads. It is during the tests results gave the samples containing the ruins of Aljufra more resistant to pressure from the samples containing the aggregate of the Sirte this can be explained by the fact that the aggregate of the Sirte contains pores more which affected the quantity of water to Hydration of cement. The results showed also that concrete with sandbank Aljufra more resistant tensile strength of the samples containing the ruins of Sirte, this can be ascribed to the surface roughness wreck Aljufra compared sandbank Sirte. It is during the tests results gave the samples containing the aggregate by 16 % more resistant to pressure the stretching of samples containing the ruins of 32 % of the amalgam concrete blocks which is expected the lack of article predators known as hyaenodontids between particles of aggregate.
