  • Effects of recycled fine aggregate content on cementitious mortar 
    Subasinghe, IS; Madusanka, VPS; Jayasinghe, VRDK; Sundarapperuma, SMAP; Fernando, WSSR; Chandrasiri, SAKN; Karunarathne, S [Conference-Full-text]
    Properties of the recycled fine aggregates and the suitability of the same in cementitious mortar were studied and compared with those of natural fine aggregates. The results showed that the particle size distribution ...
  • Effects of varying recycled fine aggregate content and water/cement ratio in bedding mortar 
    Karunarathne, S; Subasinghe, IS; Madusanka, VPS; Jayasinghe, VRDK; Sundarapperuma, SMAP; Fernando, WSSR; Chandrasiri, SAKN [Conference-Full-text]
    This paper presents the results from a research carried out with the aim of analysing the usability of Recycled Fine Aggregates (RFA) produced from Construction and Demolition Waste (CDW), in bedding mortar. Properties ...
  • Identification of optimum replacement ratio of processed quarry dust as a substitute for sand in cement plastering 
    Madhurshan, R; Anuttara, RNS; Kannangara, KKEU; Illankoon, IMTN [Conference-Full-text]
    The demand for sand is increasing due to construction activities. River sand scarcity causes illegal mining and environmental damage. The construction industry faces negative impacts if river sand becomes unavailable or ...

  • Investigation of utilization of manufactured sand in cement mortar 
    Padmasiri, DLW; Nanayakkara, SMA [Conference-Full-text]
    This paper presents results of an experimental investigation carried out to study the influence of particle shape and fines content of crushed rock fines on workability and strength of cement mortar. Different types of ...
  • The optimization of field parameters of non-explosive demolishing agent 
    Silva, DWGSL; Wikramage, KMJP; Vithanage, KS; Hemalal, PVA; Dharmaratne, PGR [Conference-Full-text]
    Demolition of concrete and rock is a common process in many construction, renovation and rehabilitation projects. Non-explosive Demolishing Material (NEDM) has been a popular alternative for explosive or mechanical demolishing ...
