Nowadays, an important objective for researchers is to find an alternative to build cheaper and greener, sustainable and also durable. To discover a material with better thermal and acoustic performances than conventional concrete by using natural and renewable components in its composition became also an obvious trend. The agriculture products, mainly those considered as waste in this field, fulfill all the above mentioned requirements, being also widely available and with higher thermal and acoustic properties t...

New building materials were obtained in the last decades by using different types of cements, aggregates, additives or additions. Additions such as s powder, aggregate, fiber, etc. were tested for obtaining new properties of concrete or for finding a way to consume the wastes. The paper presents the experimental results obtained on fly ash concrete with waste fibers. The concrete was prepared with substitution of cement with fly ash in different dosages (10%, 15%, 20%, 30% and 40%) and two types of fibers (hemp an...

This paper presents a study of performance evaluation of some fluid cement-based mortars containing mineral admixtures used as structural bonding material for fixing reinforcing steel bars in hardened concrete. The paper includes the developing of performance anchoring mortar for post-installed rebars based on ordinary blended cements. A series of standardized tests were performed within the experimental setup with the objective of assessing the performance of the mortars in terms of fluidity, cohesiveness and ear...
