CRACKING AND MOISTURE PENETRATION IN FIBRE CEMENT SHEETING. FIBRE REINFORCED CEMENTS AND CONCRETES: RECENT DEVELOPMENTS. PROCEEDINGS OF AN INTERNATIONAL CONFERENCE HELD AT THE UNIVERSITY OF WALES, COLLEGE OF CARDIFF, SCHOOL OF ENGINEERING, UNITED KINGDOM, SEPTEMBER 18-20, 1989
Cracked and uncracked polypropylene-reinforced cement specimens have been placed with one surface in contact with water and moisture penetration assessed. Water penetrated very rapidly through fine cracks in the untreated normal samples and in samples incorporating a waterproofing additive. A silane treatment applied pre-cracking was effective in preventing moisture penetration through very fine cracks, but this effectiveness reduced as crack widths increased. The silane treatment applied post-cracking prevented moisture penetration through all the crack widths studied. Cracked samples of the normal fibre cement were stored in a curing room to promote autogenous healing of cracks and re-tested. Generally, cracks had partially healed and moisture penetration was retarded.(A) For the covering abstract of the conference see IRRD 827953.
