This paper aims at the experimental study of durability properties and long-term mechanical self-compacting concrete with fly ash as secondary cementitious material copper slag inert material. Cement replaced 20% level fine aggregate 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%. Twelve different mixes were prepared to assess like RCPT, Sorptivity, UPV. The microstructure SCC was observed u...

Self-compacting concrete (SCC) is one of the most significant advances in concrete technology in the last two decades. SCC was developed to ensure adequate compaction through self-consolidation and facilitate placement of concrete in structures with congested reinforcement and in restricted areas. Marble Sludge Powder (MSP) can be used as filler and helps to reduce the total voids content in co...

As cement manufacturing accounts for 8% of global CO2 emissions, there is an urgent need to tackle the environmental impacts production and address decarbonization construction materials. Adopting supplementary cementitious materials (SCMs), including fly ash, slag, silica fume, etc., can be used as a partial replacement ordinary Portland (OPC) reduce emissions related OPC industry, while provi...

In this paper we propose a new application of Unequal Error Protection (UEP), in which UEP is used to improve channel and source synchronisation for image transmission. The source coding strategy consists of a 2-D wavelet decomposition followed by quantization and Huffman coding. Source synchronization is achieved by inserting resynchronisation markers into the Variable length Coded bit stream ...

The rapid chloride permeability test (RCPT), as it is commonly called, has been in existence for over 20 years and was standardized by ASTM over 15 years ago. The test is used extensively in the concrete industry for assessing concrete quality and is now being included in concrete specification documents. Because the underlying physics of the test are fairly well understood, it is possible to c...

In this paper, we evaluate by computer simulations the throughput performance of rate compatible punctured turbo coded hybrid ARQ (RCPT HARQ) for direct sequence code division multiple access (DS-CDMA) with antenna diversity reception and rake combining in a frequency selective Rayleigh fading channel. The impact of a range of transmission system parameters and propagation parameters (viz.: the...

In this paper, we propose the model of Scalable Joint Source/Channel Coding for wireless data transmission where channel is inherently time varying and subject to Rayleigh fading nature. We consider the problem of still image data transmission over time varying channels with two Channel State Information’s (CSI) and three bit rates ( 1, 1⁄2 and 1⁄4) for efficient transmission of data. Here, we ...

Waste management is of great concern in today’s world. Every year, an enormous amount solid waste generated from different industrial activities, especially the which produced by iron industries a particular form slag. The major issue emission carbon dioxide (CO2) cement serious problem for earth's environment and surrounding area. Thus, this study, slag obtained nearby was used as partial subs...
