properties, in particular their degradation with time. It is also invaluable in devising techniques to improve the strength and durability of concrete. Recently, it has been shown that scanning acoustic microscopy (SAM) can provide additional information [5,6] that complements classical methods of interface characterisation, such as optical
and adhered mortar content were carried out on the sieved samples with the particle sizes of 25mm to 20mm, 20mm to 15mm, 15mm to 10mm and 10mm to 5mm. Test results of physical properties of recycled coarse aggregates Test results of physical properties .
sand is very expensive and crusher sand is more economical to be used in place of river sand. In this work the mechanical properties such as flexural strength of ferrogeocrete with cement partially replaced by red mud and fine aggregate partially replaced by crusher sand is studied. Cement mortar .
locally available crusher waste without sacrificing the strength and workability of concrete. II. CONCRETE MATERIALS AND THEIR PROPERTIES Coarse aggregate of 20mm maximum size is used in Reinforced cement concrete work of all types of structures. This is obtained by crushing the stone boulders of size 100 to 150mm in the stone crushers.
Improved Concrete Properties Using Quarry Dust as Replacement for Natural Sand Anzar Hamid Mir Student, Bachelor of Civil Engineering, IUST Awantipora, JK, INDIA Abstract: Concrete plays a major role in the construction industry. Natural sand is a prime material used for the preparation of concrete and also plays an important role in Mix Design.
