Paper Title:
Effect of Super Slag Powder on Pore Structure and Compressive Strength of RPC
  Abstract

This paper deals with RPC produced by superfine slag powder(measured specific surface area is 1824 m2/kg) and natural sands with a low water-binder ratio(0.2 or so),which strength can achieve 100MPa after 28d standand curing. An analysis,based on the mercury intrusion porosimetry,is made of the relationship between strength and pore structure parameters.The results show that the strength can be improved in the range of 30~45%, when the dosage of superfine slag powder varied from 5% to 15%;the linearity between compressive strength,water-binder ratio and the hole with a daimetre larger than 100nm are 0.72 and 0.92 respectively;and the RPC’s 28-day compressive strength produced by the natural sands, with a maximum grain size of 4.75 mm,is almost equal to the RPC produced by standard sands.
