A Projection Report On The Effect Of Geometric Properties (shape) On The Strength Of Interlocking Paving Stone

CHAPTER FIVE
5.0.    CONCLUSIONS AND RECOMMENDATIONS
5.1.    Conclusions
Having established the compliance of the paving element produced with standard and specifications, one can therefore conclude that;
a.    The domineering materials commonly used for manufacture of paving blocks were stone dust, cement and water.
b.    The materials used for production are of adequate grading,     shape and texture.
c.    The effect of laterite in the mix of the laboratory produced specimens reduces both the flexural and compressive strengths.
d.    The dimensional variations were adequate while the compressive and flexural strength properties were adequate, that is, the required standard was met.
e.    The geometric properties (shape) do affect the strength of the produced interlocking paving stone.
5.2    Recommendation
1.    Production of the concrete block should be strictly supervised to ensure consistency with specified variations of ±2mm for length and breadth and ±5mm for thickness.
2.    Mix ratio of specimen (A) Bubble glover which give the highest flexural and compressive strength may be employed for production.
3.     The produced interlocking stone must be properly cured
4.    Extension of the curing age of the element must be ensured so as to increase both the compressive and flexural strengths.
5.    Laterite should not be used in the mix.
