The present paper aims to find the strength and durability properties of hybrid fiber reinforced concrete under marine conditions, and to investigate the effect of hybridization of fibres on properties of concrete. where the fibers to be used are steel fiber and polypropylene fiber and to find the proper corrosion less hybrid fiber reinforced concrete by adding the chemical admixture i.e CHYRSCO OPTIMA 9313 and MICRO SILICA to produce a moderate water reduction, better flow and retention of HYRC. Water to cement ratio increases there is a chance of high extend of having concrete permiablity, so in this investigation water to cement ratio is about 0.38 % only. The literature study reveals that there is very little literature on the durability aspects of marine conditions on hybrid fibers reinforced concrete hence lot of research is to be done. Present experimental investigation is done up to M40 grade concrete mix design. The compressive strength is one of the most important features of concrete,Compressive strength was investigated, the mix design also affected the water-cement ratio The planned technique allows the designer to estimate characteristics such as compressive strength and workability of the concrete [ABSTRACT FROM AUTHOR]

Concrete is a building material that cannot be avoided in the construction business. Massive constructions need a significant volume of concrete and substantial foundations. By substituting normal-weight concrete with light, durable, environmentally friendly, and sustainable concrete, the structure's self-weight may be reduced. Foam concrete is a material that can meet all of the following criteria. Cement, fly ash, and foaming agent are all ingredients in foamed concrete, which is a cement-based slurry that has been physically blended with a stable and uniform foam. This research investigates the target densities of foamed concrete (FC). The purpose of this investigation is to assess foamed concrete of low and medium densities. [ABSTRACT FROM AUTHOR]

Geopolymer concrete made by reacting ingredients containing silicate and aluminate with a caustic activator. Ware products such as "GGBS, flyash,& slag" from the metal and iron industries are frequently employed. Recent research has included the addition of novel ingredients such as "Alccofne", which enhance the characteristics of geopolymer concrete even at room temperature. This study gives a comprehensive review of the literature on the durability of geopolymer concrete. Various study literatures on durability of geopolymer concrete with the inclusion of various extra Cementous materials are evaluated, as their use is becoming more common as a result of persistent ingredients previous research from literature surveys revealed that substituting chemical and mineral admixtures for cement improved the strength and durability of concrete. Microstructutres,morphological structures discovered using SEM, decreased shrinkage, Stronger mechanical strengths, superior durability, and environmental sustainability are all observed. Increased polymerisation reaction, which is responsible for the growth of strength, was discovered in XRD tests. GPC controls elevated temperatures and surface degradation better than OPC. Under comparison to ordinary concrete, geopolymer concrete provides increased chemical resistance and water absorption for specimens. Sorptivity and porosity have a strong impact on the durability attributes in ambient curing circumstances. [ABSTRACT FROM AUTHOR]

Many of the high-rise buildings and tall structures are currently designed with floating columns for aesthetic intentions and to deliver additional space for mobility in parking spaces and effective utilization of working areas in a building. However, when compared to typical buildings, some of the structures are more likely to be damaged or collapse during earthquakes in high seismic zones. The soft-story, vertical or plan irregularity, Floating Column (FC), and large loads are all common features of modern multi-story buildings, whereas modern technology in the construction industry returns out to be an increasingly common practice in India's cities. Most RC structures were found to be constructed with these flaws were particularly unfavorable seismically active zones based on the findings of previous earthquake research. These outcomes occurred because of a variety of considerations, including a non-uniform distribution of mass, stiffness, and strength are all factors to consider. In this investigation, it has been compared for the analysis of multi-story buildings with and without Floating Columns (FC) at various levels in regular plans, to build a safe placement for floating columns in seismic designs. Using the software ETABS 2017, Equivalent Static Analysis (ESA) and Response Spectrum Analysis (RSA) have been performed on the Mathematical 3D model of G+10 building of a regular plan, and these models were compared, and it will assist in determining the structures numerous analytical properties as well as providing a very systematic and cost-effective design.

This study examines lightweight foam concrete compressive strength and workability by incorporating industrial waste material (Fly-ash, GGBS, Silica-fume) in different percentages. By using this surplus material, the strength of concrete increases steadily as compared to previous research papers. Rapid growth for heavy construction in the modern world leads to the development of innovative technologies in the construction sector, mainly in the production of stronger, lighter and smarter concrete. The density of light weight foam concrete generally varies from 400-1800 Kg/m3; these contribute for low strength capacity of building, roofs filling, wall filling, panels, bridge abutments, ground stabilization, tunnel infill, subway infill, stabilization of road foundation and light weight blocks. Quality of Foam concrete plays a vital role in compressive strength of concrete we used synthetic foam it was easily available outside. As per (IS CODE – 2185 PART-4) the standard size of light weight concrete bricks Length: 400,500 (or) 600mm. Height: 200,250 (or) 300mm. Width: 100, 150 (or) 200mm. Thermal conductivity:0.32-0.54W/mk. Sound insulation: 37-42db. But we done experimental on the cubes which are available in our college 150x150x150mm is done. Foam light weight concrete of low density the water resistance will be less and it float in water. We can reduce the overall cost of the construction project. The foam generated by using foam generator and due to this foaming agent, the concrete is light weight and instead of coarse and aggregate we use fine aggregate material. The study was planned to produce 1600 Kg/m3. The confirmation of the workability, strength and plasticity of the foam concrete by measuring the coated cubes after 7, 14 and 28 days of curing. This test was intended for a thickness of 1600 kg/m3. This test was obtained to ensure the workability, plastic thickness and compressive strength of foam concrete. Samples were made and tested at the age of 7,14 years and 28 days. [ABSTRACT FROM AUTHOR]

The density of foam concrete generally varies from 350-1900 kg/m3, but whereas the standard concrete density varies from 2200-2400 kg/3. This reduction within the weight of concrete results in a reduction of self-weight of the structure. Foam concrete, with restricted densities a number of building components can be replaced. The reduced density of concrete leads to lower strength when compared to standard concrete. Therefore, in these study different quantities of polypropylene fibers and Nylon fibers are used for the improvement of physical properties, and mechanical properties. In this report, foam concrete with density 1800 kg/m3 is prepared and the foam concrete is blended with different quantities of Polypropylene fibers and Nylon fibers. Different mix proportions were prepared to get the required density of foam concrete and thereafter tested for workability, plastic density, dry density, water absorption %, compressive strength were reported.

In modern developing countries there is need of high rise multi storey buildings to satisfy the needs of the newly arriving organization as well as the population migrating to the developing areas for employability. The high rise structures are vulnerable to lateral forces such as earthquake forces, wind forces, forces due explosions like atomic bombs, gas cylinders etc. considering the previous accidents among the above mentioned forces major percentage of damage is caused by earthquake forces, to ensure the safety, and comfort of the residents, the structure should be able to withstand against these forces without severe damage, without collapsing or should give prior time to evacuate the building so that the damage caused by the hazard can be prevented or reduced, In order to design the buildings that can withstand these hazards there a need to study the behaviour of the structure due to the earthquake forces. To gain proper understanding over the earthquake loads the considered structure is analyzed with respect to the seismic zones as per the Indian Standard in different types of soils (hard, medium, soft soils) [ABSTRACT FROM AUTHOR]
