Programmers have difficulty writing correct multithreaded code, not to mention code that scales well. One way to approach this problem is by offering a transaction construct, and leaving it to the compiler and run-time system to implement efficient synchronization. However, automatically generating efficient synchronization code is an open research problem. In this paper, rather than attempting...

Abstract—In this study, the effects of waste marbles as aggregate material on workability and hardened concrete characteristics of self compacting lightweight concrete are investigated. For this purpose, self compacting light weight concrete are produced by waste marble aggregates are replaced with fine aggregate at 5%, 7.5%, and 10% ratios. Fresh concrete properties, slump flow, T50 time, V fu...

A laboratory study was made of the effects of crushed particles, both coarse and fine aggregate, on the stability of bituminous-aggregate mixtures. Crushed limestone and varying percentages of crushed and uncrushed gravel were used as the coarse aggregate while variation in the shape of the fine aggregate was obtained by using rounded natural sand and crushed-stone sand. These aggregates were u...

One of the concrete technologies developed to obtain good compressive strength is additional material for iron lathe waste obtained from residue turning process. This study aims determine effect as a fine aggregate additive on concrete. The test was carried out based SNI standard 1974:2011. sample making specimens by varying 0%, 1.5% and 2.5% weight in mixture with 29.05 MPa. Concrete samples w...

This study investigates the chloride penetration resistance of fine recycled aggregate concrete (FRAC). Six mixes comprising 0.45 and 0.55 w/b were prepared using aggregates (FRA) at 0, 25 50% by volume replacement natural sand. The was tested surface electrical resistivity (SER), conductivity index (CCI), bulk diffusion tests. SER CCI tests conducted after 28 days 180 wet curing, while test ca...
