2 Lightweight - Aggregate Concretes in Compression
One research field in Leipzig deals with the design of high strength lightweight-aggregate concretes (HSLWAC). Due to the huge waveband of this concretes with all possible combinations of lightweight-aggregates and mortar matrix the formulation of general rules is difficult. Therefore both components lightweight-aggregates and mortar matrix will be investigated in detail in order to achieve a d...
متن کاملDurability of Self-compacting Lightweight Aggregate Concretes (LWSCC) as Repair Overlays
For rehabilitation of damaged concrete structures, the durability of repair overlay is a very important issue. Self-compacting concretes (SCC) are known as a suitable repair overlay materials. In this study, the durability of different self-compacting lightweight aggregate concretes (LWSCC) and effect of lightweight aggregate type on them is investigated. 3 mix designs of LWSCC containing three...
متن کاملbond strength of reinforcement steel in self-compacting concrete
self-compacting concrete (scc) is a highly fluid yet stable concrete that can flow consistently under its own weight, pass between bars, and fill in formwork without the need of compaction. the application of scc effectively resolves the difficulties of concreting in situations with complicated formwork and congested reinforcements. in this paper, the bond between scc and steel reinforcement wa...
متن کاملScaling resistance of high performance concretes containing a small portion of pre-wetted lightweight fine aggregate
The subject of the investigation was the influence of pre-wetted lightweight aggregate on damage of the concrete surface due to cyclic freezing and thawing in the presence of de-icing salts tested according to the Swedish Standard SS 13 72 44 (the Borås method). Six series of concrete specimens were made with the same water/binder (w/b) ratio 0.32, cement volume 400 kg/m and content of superpla...
متن کاملPrediction of Lightweight Aggregate Concrete Compressive Strength
Nowadays, the better performance of lightweight structures during earthquake has resulted in using lightweight concrete more than ever. However, determining the compressive strength of concrete used in these structures during their service through a none-destructive test is a popular and useful method. One of the main methods of non-destructive testing in the assessment of compressive strength...
