Abstract Secnidazole (SEC) has been suggested as an alternative agent against Trichomonas vaginalis to overcome the adverse effects, antimicrobial resistance problems and poor adherence to the currently available therapy. Once no topical formulation may be found in the market until now, SEC was incorporated in thermosensitive bioadhesive systems to extend the contact time in the mucosa and to avoid a systemic drug disposition. Formulations containing 20% poloxamer 407, 1% poloxamer 188 and 1 or ...

Abstract The pozzolanic activity and great availability of ceramic wastes (such as porcelain polishing residue – PPR) have increased their usage as supplementary cementitious material. However, studies investigating the effect of water-reducing admixtures on the early-age performance of cement-based materials containing such wastes are still lacking. This work investigated the effect of a lignosulfonate-based plasticizer (PL) and two polycarboxylate-based superplasticizers (SP1 and SP2) on the r...

Abstract The manufacturing process of pig iron generates large amounts of slag. The slow cooling of this waste generates the air-cooled blast furnace slag (ACS). Since it is less reactive than granulated blast furnace slag (GBFS), ACS finds little use as supplementary cementitious material (SCM) and the existing studies use it only as aggregates in concrete. This work investigated the use of finely ground ACS as SCM for self-compacting concrete (SCC) production. Pastes and SCCs with GBFS, ACS in...

Abstract Brazil produces 900 mi m2 of ceramic tiles annually, which generates about 60,000 tons of porcelain tile polishing residue (PPR). In previous work, the authors confirmed the feasibility of using PPR in the production of geopolymer pastes regarding mechanical and microstructural properties. This work investigated the rheological and ecological performance of geopolymer pastes and mortars produced with metakaolin replacement by PPR in 0–100%, activated with Na2SiO3/NaOH solution. Rotation...

Abstract About 35 billion tons of quarried material are produced annually throughout the world, generating large amounts of waste powders which are usually disposed of in landfills. This work investigated the feasibility of producing eco-friendly ultra-high performance cement pastes with diabase, granite and basalt quarry wastes as alternatives to quartz and limestone conventional fillers. The fresh properties (rheometry and mini slump), hydration (calorimetry, TGA and XRD), 3- and 28-day streng...

Ready-mixed mortars have been increasingly used due to their potential for waste reductions and productivity increases. However, research regarding their use in structural masonry applications are practically non-existent. Thus, this work investigated the technical feasibility of using ready-mixed mortars with nominal compressive strengths of 6, 9 and 14 MPa and storage times of 0 and 36 hours in concrete block structural masonry. The fresh state properties of the mortars were evaluated at 0 and...

Abstract The use of by-products in concrete production is a key factor for sustainable construction. However, these materials must lead to the production of concretes with adequate properties to enable their use. This work evaluated the rheological properties and surface finish quality of self-compacting concretes (SCCs) containing quarry by-product powders as fillers. For this, thirty SCCs were produced with limestone, diabase and gneiss fillers in Portland cement replacement, each one in three...

Abstract This work evaluated the effect of partially replacing a superplasticizer by silanes on the fresh and hardened properties of Portland cement pastes. For this, pastes with water/cement ratio of 0.20 and 25 and 50% replacement of a polycarboxylate-ester-based superplasticizer by tetraethoxysilane (TEOS), 3-glycidoxypropyltrimethoxysilane (GPTMS) and aminoethylaminopropyltrimethoxysilane (AEAPTMS) were produced. The specific gravity, entrapped air content and mini-slump of the pastes were d...

This work investigated the use of the <150 μm fraction of a calcined waste foundry sand (WFS) as filler in self-compacting mortars. WFS was calcined at 600–900 °C, referred to as calcined foundry sand (CFS). Self-compacting mortars were produced with cement replacement levels of 0–30 vol% with CFS and a limestone filler. WFS and CFS were characterized by X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive spectrometry (SEM-EDS) and thermogravimetric analysis (TGA). The f...
