we all know water plays a very key role in construction industry. Plain concrete needs congenial atmosphere by providing moisture for a minimum of 28 days for good hydration and to attain desired properties. Any laxity in curing will badly affect the concrete properties. The main aim of this investigation is to study the strength and durability properties of concrete using water-soluble Polyethylene Glycol as self-curing agent. The function of self-curing agent is to reduce the water evaporation from concrete, and hence they increase the water retention capacity of concrete compared to the conventionally cured concrete. The use of self-curing admixtures is very important from the point of view that saving of water is a necessity everyday (each one cubic meter of concrete requires 3m³ of water in a construction, most of which is used for curing). In this investigation, the use of water-soluble polyethylene glycol of molecular weight 400 (PEG-400) with a dosage of 0.5% to the weight of cement added to the mixing water as self-curing agent for concrete of M40 grade. The concrete was casted by replacing cement with red mud by 0%, 10%, 20%, 30%, 40% and 50% and fine aggregate by varying quantity of Quarry dust by 0%, 50%, 40%, 30%, 20% and 10% accordingly. In this study, compressive strength, split tensile strength, Non-Destructive testing (Rebound hammer) and flexural strength of self-curing concrete with replacement of red mud and quarry dust was compared with the conventional concrete specimens.

The necessity of high strength concrete is increasing because of the increasing demand of the construction materials in the construction industry. Efforts for improving the performance of concrete over the past few years suggest that cement replacement materials along with Mineral & chemical admixtures can improve the strength and durability characteristics of concrete. Silica fume is one of the materials that can be utilized to produce highly durable and economical concrete composites. This study is focused on the utilization of Silica Fume  as partial replacement of cement for the design of high strength concrete M30. After lot of trials the combination of 1:1.3:2.6 of cement, fine Aggregates and Coarse  Aggregates with 10% of Silica Fume  the desired results i.e. 14 Days Compressive strength of the Concrete cubes was found to be nearly 37.53 MPa. Hence the study proves the future generation Silica Fume as a substitute for partial replacement of normal cements (Binding Materials).

From the last millennium concrete had demanding requirements both in terms of technical performance and economy. The necessity of high strength concrete is increasing because of demands in the construction industry. Efforts for improving the performance of concrete over the past few years suggest that cement replacement materials along with Mineral & chemical admixtures can improve the strength and durability characteristics of concrete. Silica fume can be utilized to produce highly durable and economical concrete composites. This study is focused on the utilization of  Silica fume as partial replacement of cement

This paper focuses on studying the effect of glass fiber on the properties of concrete mixtures as a partial replacement of cement. The main goal is to investigate the possibility of using glass fiber as a partial replacement of cement in concrete. A series of tests were conducted to study the effect of 10% ,15% and 20% replacement of cement by  glass fiber. The compressive strength, split tensile strength and the flexural strength test were determined for the mixes at the curing age of 7 days and 28 days. The results obtained for the above mixes were compared to investigate the effects of partial replacement of cement by glass fiber. Use of glass fiber in concrete can prove to be economical.
