Autor: Paula Pérez Marfil, Darío Daniel Falcone, Silvina Andrea Marfil, Francisco Locati

Publikováno v: Bulletin of Engineering Geology and the Environment. 80:8935-8948

Determination of the potential reactivity of slow-reacting aggregates has been an openly debated subject worldwide for decades, and it remains ongoing. The province of Buenos Aires is the main producer of concrete aggregates in Argentina, and many qu

Petrographic method to semi-quantify the content of particles with reactive components and residual mortar in ASR-affected fine recycled concrete aggregates

Autor: Gabriela Coelho Dos Santos, Silvina Andrea Marfil, Francisco Locati, Darío Daniel Falcone, Claudio Javier Zega

Publikováno v: Cement and Concrete Composites. 119:104003

A petrographic method is proposed to semi-quantify the content of particles with reactive phases in fine recycled concrete aggregates (FRCA) affected by the alkali-silica reaction and the residual mortar (RM) adhered to them. This method is compared

Influence of recycled aggregates on properties of self-consolidating concretes

Autor: Carla Priano, Silvina Andrea Marfil, Lilia Señas

Publikováno v: Construction and Building Materials. 113:498-505

Recycled aggregates are made from crushed waste concretes and can be used as a replacement of natural aggregates in concrete production. Despite having lower density and higher absorption than natural aggregates, they can be used to manufacture conve

Expansive behavior of an alkali-carbonate reactive dolostone from Argentina: Proposal of an osmotic theory-based model to explain the expansion caused by the alkali attack

Autor: Silvina Andrea Marfil, Francisco Locati, Carlos Alberto Milanesi

Publikováno v: Cement and Concrete Research. 138:106239

The expansion mechanism of dolomitic rocks in alkaline environments is complex and a current topic of debate, since two different chemical reactions can coexist: one linked with silica attack (alkali-silica reaction, ASR) and the other with dolomite

Effects of different alkaline solutions on the expansivity of rock prisms of an alkali-reactive dolostone from Valcheta (Río Negro, Argentina)

Autor: Carlos Alberto Milanesi, Damián Ezequiel Benito, Silvina Andrea Marfil, Francisco Locati

Publikováno v: Cement and Concrete Research. 134:106092

A fine-grained argillaceous reactive dolostone was identified in Argentina. In alkaline conditions, a clear dedolomitization reaction occurred, accompanied by a deleterious expansive process. The purpose of this paper is to investigate the correlatio

The use of rice husk ash as a supplementary cementing material is of great interest to many developing countries where rice production is in abundance. A highly reactive pozzolan is obtained when rice husk ash is burnt under controlled conditions. Pr
