Giovanni Andrea Irico
No full textGiovanni Andrea Irico (1703-1782) was an erudite historian in the eighteenth century. For sixteen years (1748-1764) he worked in the Ambrosian Library, where he dedicated his researches mainly to the oldest sources of the Ambrosian liturgy. This paper first presents a polemical debate among some Milanese scholars about life and action of St. Ambrose. Also Irico took part in this debate with a very balanced position: in fact he was able to combine the historical rigor with respect to some popular traditions widespread at that time in Milan. But his most important work, yet unpublished, is a long comment to Ambrosian Missal: in it he re-reads the personality and qualities of Ambrose through the “filter” of the liturgical texts of the three feasts dedicated to the patron of Milan in the Ambrosian liturgical year

Animal welfare and reproductive performance in two Piemontese housing systems
No full textTie-stall and loose housing are the main housing systems adopted in Piemontese cattle farms in Piedmont Region (North Western Italy). In this study, we used the ANI35/L2000 index to assess the cattle welfare in both types of housing systems, by studying 56 farms. Within each housing system, farms were classified as 'low', 'sufficient' or 'good' welfare farms, according to the score obtained, and this score was associated with reproductive parameters of cows. A higher welfare score was obtained in loose housing farms. Calving intervals and annual calf to cow ratio showed significantly better values in the loose housing system compared to tie stalls. Within tie stalls system, better reproductive performance has been recorded in farms with a higher welfare classification
Hydration behavior of cements with reduced clinker factor in mixture with sulfoaluminate binder
No full textCO2 regulation and raw material availability will strongly influence the future cement market and a wider use of composite cements containing limestone and pozzolan or slag is expected. In the present paper, the possibility to combine Portland cements (PCs) with reduced clinker factor with sulfoaluminate cement (CSA), is explored. Low Portland clinker cements are prepared in laboratory using different supplementary cementitious materials (limestone, slag, pozzolan and fly ash) and mixed with a sulfoaluminate cement: the hydration behavior of the resulting binders is investigated up to 90 days through a multi-technique approach involving X-ray diffraction, differential scanning calorimetry and nuclear magnetic resonance spectroscopy. Understanding the interaction mechanisms between SCMs and CSA/PC blends will support the development of innovative high performing binders based on CEM III or CEM V, or even on new standardized CEM II. Results highlight that slag is particularly suitable promoting late strength development

No full textInfluence of the amount of calcium sulfate on physical/mineralogical properties and carbonation resistance of CSA-based cements
No full textBinary and ternary binders, Calcium SulfoAluminate (CSA) clinker plus anhydrite (A) and blends of Portland cement, CSA clinker, and A, respectively, are examined in order to understand the effect of the A/CSA clinker ratio (A/CSA) on hydration process, physico-mechanical properties and durability against carbonation. The study revealed that: (i) in binary systems the increase of the A/CSA has a positive influence on the physical performance, but worsens the resistance against carbonation (ii) in ternary systems a non-linear behavior related to the physical aspects is observed, being the system with the intermediate A/CSA the best performer in terms of dimensional stability and carbonation resistance. The effect of carbonation on the hydrate phase assemblage was studied through a multi-technique approach and results were supported by thermodynamic models, indicating that the optimal dosage of sulfates is strictly dependent on the carbonation exposure and the ternary systems are more durable than the binary ones
Behavior of blends of CSA and Portland cements in high chloride environment
No full textCalcium SulfoAluminate (CSA) cement has received increasing interest in recent years, mainly for its environmental aspects. However, few drawbacks such as its higher cost, compared to Ordinary Portland Cement (OPC), or the high carbonation rate, limits its application in reinforced concrete even when high early strengths are required. A technological solution could be combining CSA cement with non-corrosive reinforcements, widely used for structure exposed to marine environments. In order to evaluate the feasibility of this innovative solution even in high chlorides environments, blends of CSA clinker and limestone Portland cement were investigated in combination with seawater and varying the constituent proportions. The results show that sulfates play a key role in the equilibria between AFt/AFm influencing the Friedel's salt formation, thus the ability to bind chlorides. An optimal blend composition, able to improve the durability of concrete in marine environment, is suggested
Durability of blended cements containing sulfoaluminate clinker
No full textThe cement industry is strongly committed to a very ambitious "zero emission"trajectory maintaining the highest level of quality and durability performances. Zero emission target will be reached using several leverages, including the reduction of the clinker content in cement. Low clinker cement represent a market solution and are already efficiently implemented in many European countries, however, the strength development of low clinker cement at early age is lower compared to Ordinary Portland Cements (OPC) with higher clinker contents. The use of blends of low clinker Portland cement and Calcium Sulfoaluminate Cement (CSA) could support the need for low CO2 binder with high early strength. The behavior of four blended cements containing CSA clinker, OPC clinker, limestone, fly ash, pozzolana and slag has been characterized using different techniques in terms of resistance to carbonation, chloride migration and sulfate attack. The findings indicate that the durability performances are enhanced when supplementary cementitious materials (SCMs) with pozzolanic or latent hydraulic activity are present, as opposed to the presence of limestone. SCMs exhibit an active role also in an OPC-CSA matrix. Blend of CSA-OPC cement and slag represents a system characterized by both high early and late strengths, along with favorable durability behavior
