Precast concrete pipelines. Response against mechanical, physical and chemical attack
Concrete pipes are submitted to a number of mechanical, physical, chemical and microbiological actions. Therefore, they must be designed in order to maintain their mechanical and durable performance, volumetric stability and tightness. This paper analyses the mechanical, physical and chemical actions which can aff ect negatively to concrete pipelines used in sanitation and drainage systems.

The story of a proposal that has revolutionate the Clinker grinding industry
Cemengal has developed a modular portable grinding station that is supplied FOB in only 7 months from contract signature. The main idea of the portable grinding solution, is to be located close to the final cement consumer in small markets or new markets. Cemengal has today four different models of Plug&Grind® in the market, and shortly will be five models, and this makes Cemengal the largest and most diversify small grinding station producer worldwide.

Saudi precast company Inshaa Precast invests in high-quality tilting table production for the expansion of production capacities
The modern precast plant Inshaa Precast, based in Al-Khobar in the eastern province of Saudi Arabia, annually produces more than 500,000 m2 prestressed hollow-core slabs and processes more than 40,000 m3 concrete for a wide range of precast elements. The company decided to implement sophisticated architectural and fair-faced concrete projects and therefore required high-quality manufacturing equipment. Inshaa Precast decided to buy the tilting tables and the shuttering system from the German machine and plant manufacturer Weckenmann Anlagentechnik.

Case study: AIRCHOC® installation in Brazil
Based in Brazil, the Elizabeth group is one of the largest manufacturers of ceramics in Latin America. In full diversification, the group is currently completing in Alhandra, the construction of a new site destined for cement production. In order to avoid the different problems of clogging and build-ups that can arise in the cement production process, the Elizabeth group called on the products and services of Standard Industrie International.

Link, the new line of multipurpose safety footwear Panter, expands its range with Diamond, Eos and Altantis, its new proposals with breathable properties to beat the heat
Panter, Spanish manufacturer of safety footwear recommended during the summer, its breathable footwear to cope with high temperatures. Diamond, Eos and Altantis belonging to the new line Panter Link are ideal options to fit into this season, noted for its lightness, flexibility, and a design with vents, micro perforations, and components studied for maximum breathability.
Considerations on the corrosion rebars in a chlorides contaminated self-compacting concrete
The high significance of rebar corrosion makes further research necessary to clarify many of the aspects related to this process, not yet satisfactorily known. The present paper analyzes some aspects of corrosion of rebars embedded in a self-compacting concrete (SCC), made from sulphate-resisting (SR) cement. It has been taken into account the real situations that appear in constructions where rebars are often used with a layer of oxides in their surface.
Cement, Concrete and Circular Economy
Since the industrial revolution, waste has constantly grown. This is because our economies have used a “take-make-consume and dispose” pattern of growth, a linear model which assumes that resources are abundant, available and cheap to dispose of. What we need is a more circular economy. This means re-using, repairing, refurbishing and recycling existing materials and products. What used to be regarded as ‘waste’ can be turned into a resource.
Innovation in concrete pavements
Innovation has become one of the central elements of business competitiveness in an increasingly globalized environment, thus resulting in a diff erentiating factor for the achievement of business objectives. This article reviews the main developments that have occurred during this period and briefl y describes the new trends, focusing on porous concrete, photocatalytic, photoluminescent or electrically conductive pavements.
