dc.description.abstract | The characteristics of the fine aggregate that are present in mortar composition
significantly influence the properties of the mortars, and may change the application
yield and performance in the hardened state. Using standardized sands provided by
the Institute of Technological Research, four particle size compositions were
determined with each one having different fineness modules. The use of these 04
compositions, in an initial proportion with a ratio of 1:1:6 that are given by volume of
CPII-F 40 cement, CH-II slaked lime, sand and two levels of air-incorporating
additive, with water/dry materials constant ratio were able to generate eight types of
mixtures. Each of these tests was performed to evaluate the properties in both fresh
and hardened state, also aiming to evaluate the influence of the variation of the
fineness module on the properties. Related to the fresh state, the increase of the
fineness module caused the increase in the entrained air content, decrease in water
retention, higher consistency index and lower energy needed for spreading. Related
to the hardened state, the observed effects regarding to the compressive strength
and adhesion were more influenced by a better particle size distribution rather than
by a variation of the fineness module. Permeability attributed to water and steam was
higher in mortars composed of sand with larger fineness modules. Shrinkage
indicators showed a decreasing trend as the fineness module increased. | |
