Abstract: This study has been carried outto find out the details of development of variousphysical properties of geopolymer. Compressivestrength, water absorption and sorptivity are some ofthe most important physical properties which are broadly discussedhere. Grey Fly Ash (Class F) is the main constitute material of this geopolymer. Potassium hydroxide and sodiumsilicate are used here as activator. Percentages of alkali changes in grey fly ash have made anobvious impact on it. This below investigation is broadly depends upon the variation in silicate modulus and also percentage of K2O but with fixed sample of fly ash. The details and discussion of the experimented properties are discussed below broadly.

Abstract: From the year 1999, the PMGSY under Govt. of Republic of India is sanctioned project on in each part of the country for better communication system and transportation facilities. Under such circumstances a big amount of road construction is needed, specially in rural areas. Considering the poor subsoil condition in some of the districts of state, is extremely poor. Now the major parts of the roads are made over the sub grade soil. Sub grade is used as the bottom most layer of the pavement like Rigid or Flexible........

Abstract: Specifically in India, Soil generally present is Clay. Where in Various construction works are sincerely proves intricate because of swelling and shrinkage traits of Clayey soil. In this situation, frequently we do not have some other options other than Stabilizing the Soil. In modern-day technology, lot's of Chemical stabilizers are frequently practiced, however these are often high-priced and unhygienic in terms of environmental sustainability. The prevailing investigation has therefore been completed by using Rice Husk Ash(RHA) and Lime.........

Country	:	India
Authors	:	Priyanka Deb Sinha || Riya Bhattacharyya || Partha Pratim Sarkar

Abstract: This paper presents a novel proposal for the design of a double layered Frequency Selective Surface (FSS) for broadband applications. The structure of the proposed FSS has been designed using two different steps. The first step comprises of designing two separate FSS structures to resonate at 10.97 GHz and 7.53 GHz, with a percentage bandwidth of 34.73% and 55.77% respectively. In the second step these two structures are cascaded in order to attain broadband characteristics........

Country	:	India
Authors	:	Epsita Kar || Debabrata Dutta

Abstract: The objective of this manuscript is to study the strength & deflection performance of bamboo reinforced concrete member under flexural loading. Bamboo is used as an alternative of steel as a reinforcing material to confirm its tensile strength and bond strength. This is an empirical study oriented, time consuming and rigorous attempt and the documentation involved previous case studies as reported in civil engineering journals of repute. The consequences are categorically tested and the authors advocate for the use of bamboo reinforced concrete member under flexural loading.

Title	:	Activated FA Blended With Black Cotton Soil – an Ecological Substitute of Binder in Roadway
Country	:	India
Authors	:	Dr.S.K.Sarkar || D.Dutta || Dr. T.G.Biswas

Abstract: Owing to its low initial cost, flexible pavements have been preferred in compare with rigid pavement. In the recent era, the insufficiency of raw materials and growing rates of bitumen are become a great problem. Now the benefits of rigid pavement is well recognized. But only disadvantage for concrete rigid pavement is the initial cost which is around 30% more than flexible pavement. For rigid pavement LCC (lifecycle cost) is much lesser than flexible pavement. Our industry is seeking for a true substitute which is sustainable and economic. In this study a typical non- conventional composite is developed by presenting Class C Flyash and Black cotton soil in alkaline medium.........

Authors	:	Juthi Basak || Argha Nag || MrigankaSekhar Banerjee || D. Dutta || Dr. T. G. Biswas

Abstract: This investigation explores the comparative studies of harden properties of typical fly ashes i.e. black, grey and white. This research shows that the parametric study of geo-polymer paste resulting from controlled percentage of alkali activator. The activator is prepared by mixing of Na2SiO3 and KOH solution. For every case activator subjected to a constant temperature 27°C stands for 24 hours. The geopolymer sample were mixed in a predetermine mix proportion. Then the sample were casted in a mould and it was cured for 24hours 85°C. To know the parameters like characteristic strength, water absorption, sorptivity the experiment was conducted.

[1]. Compressive strength of GPBF fly ash sample is higher than GPGF and GPWF fly ash sample. The strength of GPBF fly ash is 36Mpa. The strength of GPGF and GPWF fly ash sample 12Mpa and 10Mpa respectively. Gained strength is propotional to polymerization while the rate of polymerization directly depends on the presence of reactive silica.

[2]. Water absorption valueof GPBF and GPGF are 4.6% and 6.4% respectively.Geopolymer of Black fly ash is consuming less amount of water than geo-polymer of grey fly ash.It indicates less permeable pores for sample GPBF.
[3]. The apparent porosity is less for GPBF which again supports the lower intrusion of moisture through pores.
[4]. The geo-polymer specimen of black fly ash exihibits lowersorptivity index 0.144 than that made of grey and white.Sorptivity value is higher forgeopoymer made from gray and white fly ash.In fact higher calcium content in geopolymer induce secondary CSH product which makes reduction in meann median pore size, which in fact affect surface tension as well as sorptivity.
