In this work, the influence of a modification and fillers on dimensional stability warpage semi-crystalline polypropylene compounds in screw-based Large Area Additive Manufacturing is investigated by material characterization experimental testing. Polypropylene modified blending an amorphous polyolefin-copolymer as well addition three different talc, glass fibers, hollow beads, resulting eight ...

Cementitious composite is one of the most widely used construction materials in the world because its abundant resources, strong adaptability and mature production process [1]. Despite cementitious matrices present good compression strength, they are brittle and usually break when suffer some strain caused by tensile effort. Aiming to overpass this problem some fibers can be used as reinforceme...

In this study, first by surveythe parameters affecting the compressive strength, such as water to cement ratio, cementgrade, silica fume to cement percentage, and the various ratios oflight weight aggregate LECA, to total aggregate, Taguchi method is used, to test 9 mix designsobtained the mix design optimization. Since lightweight concrete is brittle like normal concrete, to resolve this probl...
