Effects of Nigerian Limestone and Superplasticizer on the Hardened Properties of Self Compacting Concrete
Keywords:
Self Compacting Concrete, Limestone powder, Compressive StrengthAbstract
The durability of concrete structures has posed a problem of great
significance all over the world and the Nigeria’s construction industry is
highly plagued by this problem as can be testified by the numerous
collapsed concrete structures verified in Nigeria in the past few years.
Good concrete works require good production process by skilled workers;
however, the inadequacy of the needed skilled workers in Nigeria’s
construction industry is evidenced in poor quality of concrete construction
works and the massive importation of cheap and partially skilled labour
from neighbouring countries. This research studies the properties of selfcompacting concrete (SCC) at different replacement levels of cement
with limestone powder. Theinfluence of Nigerian limestone powder in
this SCC is tested and the compressive strength of the SCC compared to
that of normal concrete. Results obtained are good and predicts that the
use of Nigerian limestone powder can improve the quality of concrete
used in Nigeria construction industry and elsewhere in the world.
