3. The 28 days average compressive strength of concrete paving blocks as obtained are above the minimum average 28 days compressive strength calculated as per IS 15658:2006 and Dowson 1980. 4. Thus, the mix design procedure followed in this research study may be used by manufacturers for producing concrete paving blocks. REFERENCE [1].

Compressive strength* When both the following conditions are met, the concrete complies with the specified compressive strength; i) The mean strength determined from any group of 4 consecutive samples (4×3 = 12 cubes specimens) at 28 days should exceed the specified characteristic compressive strength by 3 MPa (N/mm 2).
Information from the National Ready Mixed Concrete Association. Flexural strength is one measure of the tensile strength of concrete. It is a measure of an unreinforced concrete beam or slab to resist failure in bending. It is measured by loading 6 x 6inch (150 x 150 mm) concrete beams with a span length of at least three times the depth.
Specified Compressive Strength of Concrete Masonry, f'm (psi) According to the Code this would require a block compressive strength of 1900 psi Recently on projects, some designers are now specifying a higher f'm, ie, Contact Supplier; Concrete Interlocking Paving Blocks Compression Strength .
Concrete paving blocks. Requirements and test methods. It is applicable to precast concrete paving blocks and complementary fittings for pedestrian use, vehicular use and roof coverings, footpaths, precincts, cycle tracks, car parks, roads, highways, industrial areas (including docks and harbours), aircraft pavements, bus stations, petrol filling stations.
This method describes the procedure for determining the compressive strength of concrete using portions of beams broken in flexure for the test specimens. Except for editorial differences, the procedure described is the same as ASTM C 116 and AASHTO T 140. This test method is intended for use in the laboratory and as a research tool for determining
reinforced steel bars imbedded in concrete .A total of 72 cubes were cast to determine compressive strength and 24 cylinder to determine the indirect tensile strength. Bond strength between reinforcing bars and concrete was determined by pullout test on 24 concrete blocks. Corrosion rate was studied and the results are presented.

Studies have focused on the properties of concrete paving blocks prepared with recycled concrete aggregates, commonly found in the construction and demolition waste, examining several properties such as, density, compressive strength, tensile splitting strength, water absorption value, abrasion resistance and skid resistance.
However, tensile strength of concrete is very low in compared to its compressive strength. Due to difficulty in applying uniaxial tension to a concrete specimen, the tensile strength of the concrete is determined by indirect test methods: (1) Split Cylinder Test (2) Flexure Test.

SANS Specifications for Concrete paving bricks. 1. The manufacturer has an equipped laboratory and tests batches of manufactured blocks. 2. Blocks comply with strength specifications which are tested by means of tensile splitting. 3. Blocks comply with abrasive resistance specifications. This means that blocks are only allowed a specified amount of "damage" due to friction.

Thus, compressive strength of typical units could vary between 2000 psi () and 4000 psi. ( MPa) Standard Methods of Sampling and Testing Concrete Masonry Units (ref. 11) can be referred to for determining strength of drystack units.
This test method covers determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. It is limited to concrete having a unit weight in excess of 50 lb/ft 3[800 kg/m ]. The values stated in either inchpound or SI units are to be regarded separately as standard. The SI units are shown in
