    Abstract: In an attempt to improve the production of concrete and make its mixing easy, a 700 mm × 530 mm drum size of a concrete mixing machine was designed and fabricated. The machine parts were made of mild steel, because of its availability and versatile machinability. The efficiency was examined using cement, sand and coarse aggregate with water was add... Show More

    Abstract: Surface temperature is a highly desired but difficult measurement especially in concentrated solar context. In this work a method for surface temperature measurement based on contact sensors is presented. In the case of materials with high thermal conductivity, contact sensors positioned in the back of the material sample and very close to the surf... Show More
