主　　题：cement strength tile/brick dust self-compacting fiberized mortar 

摘      要：It is known that clay-based building materials such as bricks and tiles accumulate in landfills at the end of their useful *** an alternative,recycling clay-based building material can reduce the negative environmental *** brick powder(RBP)is obtained by grinding waste brick and tile collected from end-of-life *** the scope of the study,the use of self-compacting fiber reinforced mortars(SCFRMs)produced with RBP using CEM-I 42.5R and 52.5R class cements for two different cement classes was *** accordance with EFNARC,a water binding ratio of 0.42 was used to control the workability and strength of the *** the produced SCFRM,1%,2%,and 3%by weight binder Polypropylene(PP)fiber was added to the blends with 10%,20%,and 30%RBP substitutes.A total of 32 SCFRM mixes were produced and *** flexural and compressive strengths at 7,28,56,and 90 d were evaluated on the produced *** addition,porosity and water absorbency values were examined since these are significant for durability *** was observed that the use of RBP increases durability,and the use of fiber can have positive effects in terms of both durability and strength.
