    Residual Mechanical Properties Of Concrete Made With

    This paper presents the residual mechanical properties of concrete made with crushed bricks and clay roof tile aggregates after exposure to high temperatures. One referent mixture and eight mixtures with different percentages of replacement of natural aggregate by crushed bricks and roof tiles are experimentally tested. The properties of the concrete were measured before and after exposure to

    Effect Of Crushed Tiles Aggregate And Oil Palm Additive On

    The use of waste material as aggregates in civil engineering applications is beneficial and is becoming increasingly desirable because it reduces the environmental impact and economic cost of quarrying operations processing and transportation. Thus this study focused on establishing the effect of crushed tile and oil palm fibre additive on the compressive and flexural strength of concrete.

  • How Does Aggregate Properties Affect Concrete

    How Does Aggregate Properties Affect Concrete

    Concrete is more workable when smooth and rounded aggregate is used instead of rough angular or elongated aggregate. Crushed stone produces much more angular and elongated aggregate which have a higher surface to volume ratio better bond characteristics but require more cement paste to produce a workable mixture.

  • Strength

    Strength

    Concrete mixtures containing rough textured or crushed aggregate would show somewhat higher strength at early ages than corresponding concrete containing smooth or naturally weathered aggregate of similar mineralogy. A stronger physical bond between the aggregate and the hydrated cement paste is assumed to be responsible for this.
