Abstract:

This paper evaluates the self-compactibility of flowing sand-concretes (FSC) mixtures, incorporated various dune sand and marble powder contents, by testing flowability (determined by slump flow and v-funnel tests), passing ability (determined by L-box test) and segregation (determined by the visual stability index). The compressive strength at 28 days was also determined. Results show that the slump flow of all FSC mixtures lie between 450 and 840 mm, thus satisfying flowability according the recommendations of AFGC, except for the mixture made with 150 kg/m3 of marble powder (with a slump fl

Abstract:

This study describes two workability tests, compressive strength and tensile strength tests of high strength flowable concrete containing plastic fiber prepared from polyethylene terephthalate (PET) waste bottles.

Results show that there is a Vebe time increase with PET fiber addition to concrete being increased with increasing fiber volume and fiber length. V-funnel time was found to reduce when up to 0.75% fiber volume is added to concrete, followed by an increase for larger fiber volumes. When fiber length is incr

Abstract Self-consolidating concrete (SCC) is one of the trending low-yield stress material innovations of the new age building industry due to its ability to flow through heavily reinforced structural members without segregation and without losing its moderate viscosity.

Abstract We present an observational study of the formation and disappearance of a funnel prominence. Before the funnel prominence formed, cool materials from the top of a preexisting polar crown prominence flowed along saddle-shaped coronal loops to their base, forming a smaller prominence. Meanwhile, the saddle-shaped coronal loops gradually rose, and U-shaped coronal loops, termed prominence horns, began to appear along with a coronal cavity. Afterward, a cool column emerged from the chromosphere, rose vertically into the corona, and then moved laterally to be transported into the U-shaped

Abstract:

This study emphasizes the effect of viscosity modifying agents (VMAs) on bleeding and dewatering of fresh mortars under high pressure. A detailed experimental dewatering device was designed and the analysis was carried out in order to evaluate the influence of two types of VMA on dewatering of freshly mixed mortars under high pressure. Additionally, the influence of the VMAs on mortar flow and air content of concrete was investigated. Two different types of VMA, which are a surfactant type and a starch ether type with various dosages were used in the tested mortar and concrete sample having th

Abstract This research assessed the rheological properties of aluminium dross in self-compacting concrete. Aluminium dross, solid waste from the aluminium processing industry, was used as a partial replacement for cement in the development of eco-friendly concrete. This was done in a bid to reduce the cost of management of this waste in track with the ‘waste to wealth’ initiative. In this article, aluminium dross was used as a partial replacement for cement at 0, 4, 8, 12, 16 and 20% content.

Abstract:

The purpose of this study was to investigate the relationship between molarity and workability in Self-Compacting Geopolymer Concrete (SCGC), as well as mechanical properties. Compressive strength and split tensile strength tests are used to characterize the mechanical characteristics in this research. Additionally, the study investigates the optimal molarity for self-compacting geopolymer concrete. Fly ash was used in lieu of cement in this research. On new concrete self-compacting geopolymer, workability is determined using the EFNARC standard, which includes the Slump Flow, V-Funnel, and L-

Abstract:

The ever increasing environmental challenge arising from improper waste management has been a great concern to researchers and the society. One of such industrial waste is micro silica; a bye-product of the Carbothermic reduction of high purity quartz at temperature of about 2000oC in the presence of coke. The finess of this material and its pozollanic nature makes it suitable for use in the production of self-compacting concrete. In this research micro silica was introduced in percentages of, 5, 10 and 15% as partial replacement of cement in the production of self-compacting concrete. The fre

Currently, there are a variety of test methods to evaluate the plastic properties of self-consolidating concrete (SCC) specified in provincial, national, and international guidelines. There is, however, a dearth of knowledge on how the results of the various test methods compare with each other. Some of the tests are direct measures, others are indirect; some of the tests are qualitative and others are quantitative; and some tests have specified acceptance limits while others do not.

Approximate analytical closed energy formulas for semirelativistic Hamiltonians of the form [Formula: see text] are obtained within the framework of the auxiliary field method. This method, which is equivalent to the envelope theory, has been recently proposed as a powerful tool to get approximate analytical solutions of the Schrödinger equation. Various shapes for the potential V(r) are investigated: power-law, funnel, square root, and Yukawa. A comparison with the exact results is discussed in detail.

Different properties of Self-compacting concrete (SCC) containing plastic waste aggregate (PWA) have been experimentally studied by researchers.

In the present paper, the influence of four different types; namely Polyvinyl chloride (PVC), Heat-treated plastic (PEL), Mixed plastic (Mix), and polyethylene terephthalate (PET) as a fine aggregate (FA) replacement; on fresh properties of SCC was examined. Results indicated that changing the PWA geometry influenced different properties of SCC. All concrete samples wi

We investigated the influence of adding calcium carbonate powder (CCP) to self-compacting mortar (SCM) mixtures. Type 1 Portland cement was replaced with 0%, 20%, and 40% as-received or ground BA and CCP by weight. Mixtures were designed to yield a slump flow spread of 25.0 cm in diameter. The water requirement and V-funnel flow time of each SCM mixture were determined.

There are several methods for testing it's properties in the fresh state: the most frequently used are slum-flow test, L-box and V-funnel. This work presents properties of self-compacting concrete, mixed with different types additives: fly ash, silica fume, hydraulic lime and a mixture of fly ash and hydraulic lime.

However, wind energy is not as popular as solar energy, as the main renewable energy source in Malaysia, due to the relatively low wind speed available in the country. The INVELOX machine, introduced in 2014, was one of the most recent systems used to harvest wind power by accelerating wind speed. This omni-directional wind funnel could
