PROPERTIES OF CONCRETE CONTAINING GROUND GRANULATED BLAST FURNACE SLAG (GGBFS) AT ELEVATED TEMPERATURES

Bearing in mind the convoluted interactions among energy fluxes and radiations at land surface, it is very difficult to describe how the groundwater thermodynamically affects each of them separately. Though, if we keep in mind the instantaneous nature of those interactions, w[r]

In the present study, the risk of alkali silica reaction of ultra-high performance concrete (UHPC) was assessed in NaOH solution and accelerated climate condition. The UHPC containing rice husk ash (RHA) with and without ground granulated blast-furnace slag (GGBS) were used.

To improve upon the physical performance values at the connection point, there are several options to choose from. One of the best ways to provide ultimate connector performance is to terminate the fiber with factory connectorized pigtails. A pigtail is nothing more than a factory te[r]

For the preparation of PU’s, saccharides such as glucose, fructose and sucrose were first dissolved in PEG 200 (molecular mass 200) or PEG 400 (molecular mass 400) at 323 or 333 K. Prior to reaction with MDI, the polyol solutions of saccharides were dried under vacuum with vi[r]

The thermophysical properties of graphene nanofluids in thermosyphon have been studied at different power inputs, temperatures and angles of inclination. The thermal conductivity of the graphene nanofluid is found to be 29% higher than that of the deionized water at 45 0C.

This study investigated the synergy in shear response of ultra-high-performance fiber-reinforced concrete (UHPFRCs) containing different contents of long and short smooth steel fiber reinforcements at high strain rates.

The research aims at proposing an innovative application of using Fourier transform infrared (FTIR) to examine the microstructure of a new no-cement SFC binder paste, which is fabricated with mixture of ground granulated blast furnace slag (GGBFS).

Ultrahigh performance concrete (UHPC) usually contains a very high proportion of ordinary Portland cement which
requires a high amount of energy for its production. The present investigations aimed at systematically developing UHPC
