dc.description.abstract |
Paving blocks are used as a top layer of road structures to replace asphalt. Concrete
paving slabs are usually made by mixing materials such as Portland cement or
other bonding materials, water and aggregates. Compared to other pavements such
as concrete or asphalt, there is an increasing demand for paving blocks. The
advantages of paving blocks include environmental friendliness, aid in soil
conservation, fast completion time, easy installation and maintenance, aesthetic
beauty and low cost. This research aims to prepare paving blocks using
Aruwakkalu red sand and lime stone as coarse aggregates and fine aggregates
instead of stone aggregates and river sand. Samples were prepared using a mixture
of limestone and red sand using cement: fine aggregate: coarse aggregate mixing
ratio of 1:2:2. The maximum compressive strength of 60.1 MPa in 28 days of
curing time for grade 50 mix design. Trial mixes were cast and tested for
compression after 7 days and 28 days of curing time. Paving blocks are mix
designed as per the DOE concrete mix design method. Quantities of constituents
were estimated for characteristic compressive strengths of 40 N/mm^ and 50
N/mml 40 N/mm^ was selected for the class B roads and 50N/mm was selected
for the class A roads. |
