Gerhard Kurlemann,Hubertus Kursaweelop geopolymer concrete (GPC) works is carried out. In this attempt, 80% of washed brick (BW) and concrete (CW) waste is reused to prepare GPC. Firstly, the X-ray fluorescence (XRF) analysis summarises the chemical composition in BW and CW. The alkaline activation 12 molarity sodium hydroxide and N

Gerhard Kurlemann,Hubertus Kursawes a rougher surface than natural aggregates, is a denser waste product of the steel foundry and allows for greater particle conformance to the cement matrix. Due to silica sand‘s ability to fill tiny spaces, the pores in concrete are reduced by increasing the density of the concrete. This research s

The main objective of the research is to investigate the coefficient of pressure distributions over the NREL S809 profiled airfoil blade at a freestream velocity of 12 and 20 m/s using low-speed subsonic wind tunnel. There are two configuration

Martin Reichenecker,Bernhard Schweizere current study at a hypersonic Mach number of 10. The aerodisk diameter is described as d/D ratios such as 0.2, 0.4 and 0.6, and the length of the aerospike is represented as the L/D ratio of 1, 1.5 and 2. The main objective of the research is to examine the aerodynamic properties of blunt noses wi
