This paper presents part of a research into the small scale modelling of masonry. Small scale testing of masonry has been carried out by many authors, but few have attempted a systematic determination of the parameters that affect masonry at a small scale. The effect of increasing mortar strength and different sand gradings under compression were investigated. The results show masonry strength ...

this paper investigated the effects of combining fibers with self-consolidating concrete (scc). 12 series of test specimens were prepared using three kinds of fibers including steel, polyphenylene sulfide (pps) and glass fibers with four different volumes fractions and one specimen without fibers as a reference sample. all plans were subjected to fresh concrete tests. for mechanical behavior of...

Ureolytic microbial-induced calcium carbonate precipitation (MICP) is a promising green technique for addressing sustainable building concerns by promoting self-healing mortar development. This paper deals with bacteria-based under artificial seawater incubation the sake of fast crack sealing sufficient resource supply. The ureolytic MICP mechanism was explored morphology characterization and c...

A microcapsule-type self-healing protective coating with secondary crack preventing capability has been developed using a silanol-terminated polydimethylsiloxane (STP)/dibutyltin dilaurate (DD) healing agent. STP undergoes condensation reaction in the presence of DD to give a viscoelastic substance. STP- and DD-containing microcapsules were prepared by in-situ polymerization and interfacial pol...

Cultural self-confidence is ultimately people's recognition of national cultural values, which means that the study must pay more attention to "people". Therefore, this paper applies Marxist anthropological theory interpret from three levels human development, value and needs, accordingly proposes in development self-confidence, we should know status "people", influence play subjective role Acc...

In this paper we investigate relations between several masking schemes. We show that the Ishai–Sahai–Wagner private circuits construction is closely related to Threshold Implementations and the Trichina gate. The implications of this observation are manifold. We point out a higher-order weakness in higher-order Threshold Implementations, suggest a mitigation and provide new sharings that use a ...

Masking schemes are a prominent countermeasure to defeat power analysis attacks. One of their core ingredients is the encoding function. Due to its simplicity and comparably low complexity overheads, many masking schemes are based on a Boolean encoding. Yet, several recent works have proposed masking schemes that are based on alternative encoding functions. One such example is the inner product...

In this study, the influence of mechanically activated electric arc furnace slag (EAFS) was investigated through compressive strength tests on 50 mm mortar cubes. The objective was to convert the wasteful EAFS into a useful binding material to reduce the cement content in concrete without compromising strength and economy. Four different groups of mortar were cast which include control mortar, ...
