1. Alkaline activation of high-calcium ash and iron ore tailings and their recycling potential in building materials
Resumo Materiais álcali ativados são aglomerantes obtidos a partir da ativação alcalina de precursores ricos em alumínio e silício. Os precursores mais comuns utilizados para ativação são as cinzas com baixo teor de cálcio, as escórias de alto forno e o metacaulim. Contudo, a cinza de cavaco de eucalipto (CCE) e o rejeito de minério de ferro (RMF

2. Silicon and boron mitigate the effects of water deficit on sunflower
RESUMO Objetivou-se avaliar o efeito do silicato de Ca e Mg e do B sobre as trocas gasosas, potencial hídrico foliar e parâmetros da fluorescência da clorofila na variedade de girassol Embrapa 122-V2000, em condições de deficiência hídrica. O ensaio foi realizado em Latossolo Vermelho-Amarelo de textura muito argilosa, com níveis contrastantes de Si

3. Effect of addition of nano-hydroxyapatite on physico-chemical and antibiofilm properties of calcium silicate cements
ABSTRACT Objective Mineral Trioxide Aggregate (MTA) is a calcium silicate cement composed of Portland cement (PC) and bismuth oxide. Hydroxyapatite has been incorporated to enhance mechanical and biological properties of dental materials. This study evaluated physicochemical and mechanical properties and antibiofilm activity of MTA and PC associated with z

4. Effect of silicate fertilization on soil and on palisade grass plants under grazing intensities
Application of calcium silicate (SiCa) as soil acidity corrective was evaluated in a Rhodic Hapludox soil with palisade grass conducted under pasture rotation system with different grazing intensities. Experimental design was complete randomized blocks with four grazing intensities - grazing intensities were imposed by forage supply (50, 100, 150 and 200 kg

5. Estudo e caracterização de matérias-primas para o desenvolvimento de blocos sílico-calcários
The types of products manufactured calcium silicate blocks are very diversified in its characteristics. They include accessory bricks, blocks, products in dense material, with or without reinforcements of hardware, great units in cellular material, and thermal insulating products. The elements calcium silicate are of great use in the prefabricated constructi

7. SilÃcio na produtividade e no controle da cigarrinha-das-raÃzes Mahanarva fimbriolata Stal em cana-de-aÃÃcar / Silicon on the productivity and on the control of the spittlebug Mahanarva fimbriolata StÃl of sugarcane
The advent of automated sugarcane harvesting, and its replacement of traditional pre-crop burning, has created a favorable environment for the spittlebug Mahanarva fimbriolata StÃl. The spittlebug was previously considered a problem just in the sugarcane plantations of northeast Brazil, but it has now become one of the main problems for this culture in the
