Properties of concrete blocks prepared with low grade
In the study reported in this paper, three series of concrete block mixtures were prepared by using the low grade recycled aggregates to replace (i) natural coarse granite (10 mm), and (ii) 0, 25, 50, 75 and 100% replacement levels of crushed stone fine (crushed natural granite <5 mm) in the concrete blocks. Test results on properties such Particle packing was identified as the key factor affecting concrete block performance. • Packing optimization yielded 31% increase in packing and 156% increase in strength. • The strength of recycled aggregate concrete is 94% of that of natural aggregate concrete. • Empirical prediction equations for properties of concrete paving blocksEffect of natural and recycled aggregate packing on properties

The main properties of concrete blocks are compression and tensile strength, absorption, dimensional accuracy, density, and shrinkage (Parsekian et al., 2012). In relation to density, units with a density of less than 1700 kg/m 3 are usually classified as lightweight, while normal weight blocks are those with a density greater than 2000 kg/m 3 .The concrete abrasion resistance is primarily dependent on its compressive strength as observed from various studies done earlier [10,13]. Concrete strength is dependent on factors such as air entrainment, water to cement ratio, type of aggregates and their properties, therefore it should also influence the abrasion resistance.Strength properties of concrete blocks with Sand

Properties of concrete paving blocks made with waste marble
Concrete paving blocks are produced based on a mixture of Portland cement, natural fine and coarse aggregate. There has been before us some work on applying marble waste. Thus, Alyamac and Ince (2009) as well as Topcu and coworkers (Topcu et al., 2009) studied the feasibility of using waste marble dust as a filler in self Section snippets Experimental programme. In order to compare the strength and deformation properties of concrete masonry bonded with different mortar grades (M2, M3 and M4) and bedding types (full and face-shell), three courses high masonry prisms were constructed using two different types of blocks (solid and hollow).Compressive strength and deformation characteristics of concrete block

Study on the properties variation of recycled concrete paving block
According to the requirements of the standard [12] and the applications of concrete paving blocks, five important properties of concrete paving blocks, compressive strength, tensile splitting strength, water absorption, slip resistance, and abrasion resistance were tested in this series of experiments following the methods on British standardFor concrete blocks, the compressive strength is typically around 17.5 N/mm2 or 2500 psi. This means that the blocks can support a load of up to 17.5 N per square millimeter before they start to crack. Compressive strength is tested to determine how much compression a concrete block structure can endure.Compressive Strength of Concrete Block: Everything You
