“…June 2023, Vol.7 No.17 10-14 For example, the study by Maaze and Shrivastava (2023) shows how fly ash geopolymers are a sustainable substitute for raw clay brick; another material is plastic powder, supplanting the 7.5% mass of clay, which is reported to make bricks that are lightweight, with greater durability to water absorption and volumetric stability (Idrees, Akbar, Saeed, Gull, & Eldin, 2023). It is important to mention that, of the 770 tonnes per day of solid waste, 7.7% is plastic, of which only about 30% is collected for reuse (UN Environment programme, 2021).…”

The peripherals illegal settlements in Puebla, have common denominator to born in a situation of urban vulnerability, it means with a lack of infrastructure and basic services and on some occasions on land not suitable for urbanization. This is the case of the Cuitláhuac neighborhood where approximately 400 inhabitants live. The neighborhood only has electricity service, his high urban vulnerability becomes worst in the rainy season with the formation of gullies, flooding sites and soil erosion, affecting the mobility of the inhabitants. Authorities ignore these problems and not always included them in urban development plans. The objective of research is to look for environmental alternatives to reduce urban vulnerability in illegal settlements. The methodology is based on action research and the main techniques were: documentary review, physical and virtual field trips, virtual meetings and semi-directed interviews. A relevant conclusion is that green infrastructure is feasible and can be implemented in the short term and that it arouses much collaborative interest from the inhabitants both for its implementation and for its maintenance.

“…Fibre reinforcement improves the load-bearing capacity, abrasion resistance, and fracture toughness of the specimen as well as the mechanical and ductility properties of the geopolymer composites. The most widely used fibres are steel, PVA, basalt fibres, and some natural fibres as well [ 11 , 12 ]. The main point of fibre additions to geopolymer composites is to increase the tensile strength and flexural strength.…”

This study investigates the cyclic load application impact on fly-ash-based geopolymer composites that are reinforced with a low amount of fibre reinforcement. For reinforcement purposes, polyvinyl alcohol and steel fibres are used. For testing purposes, four geopolymer composite mixes were made, three of which had fibre reinforcement. Simultaneously, specimens were tested for shrinkage, static-load-induced creep, and cyclic-load-induced creep. For static and cyclic creep testing, specimens were loaded with 20% of their strength. For cyclic creep testing, load application and release cycles were seven days long. When each cycle was introduced, the load was applied in steps. Necessary load application or unloading lasted for 5 min and consisted of four steps, each 25% of the necessary load. From the long-term static and cyclic creep tests, it was seen that only the plain specimens showed that static creep strains are within cyclic creep strains. For all the other specimens, the static load was higher than the cyclic-load-induced creep amplitude. Also, 1% polyvinyl alcohol fibre-reinforced specimens showed the most elastic characteristics under cyclic load, and 1% steel fibre-reinforced specimens appeared to be the most resistant to the cyclic load introduction.
