Definitions
- the present invention falls within the field of ultra-high strength concrete reinforced by incorporating metal fibers in the mixture.
- the concrete of the present invention finds a particular application, although not limited thereto, in the production of prefabricated facade panels for buildings made with highly industrialized procedures.
- Ultra high strength concrete reinforced with the incorporation of steel fibers called UHPFRC by its acronym in English (ultra high performance fiber reinforced concrete), has been known since at least 1990.
- the present invention provides a new concrete formulation, alternative to those known in the state of the art and specially adapted for application in buildings with prefabricated panels or panels.
- the UHPFRC concrete of this invention aims to provide the following mechanical properties:
- the materials used comprise two types of cement in a preferred embodiment: Portland gray cement from UNILAND and Portland gray cement from CEMENTOS MOLINS, in accordance with the following specifications:
- REPLACEMENT SHEET (Rule 26) say compressive strength at 28 days, minimum 52.5 Mpa, with values of 58 MPa being usual,
- PVA polyvinyl acetate
- Fig. 1 shows the results of the concrete runoff test for the fresh state characterization of the UHPFRC concrete of this invention.
- Fig. 2 shows the results of compressive strength of concretes manufactured in accordance with this invention.
- Fig. 3 shows the tensile strength results of said concretes.
- - natural calcium carbonate is made from selected calcite, with a high degree of purity, low iron oxide content and absence of heavy metals; OMYACARB -12 Cl is used, which is characterized by its wide range of particle sizes and its purity; the chemical composition of the raw material contributes 97% of CaC0 3 and the residue in the 100 micron sieve is less than or equal to 0.5% and the residue in the 45 micron sieve less than or equal to 10%; Production plant company L'Arboc (Tarragona - Spain);
- the nanosilica is Rheomac VMA 350 (additive based on a dispersion of spherical nanoparticles of pure silica dioxide, free of
- Table 1 is shown below which shows the adjustments in the initially planned dosages and some tests with PVA fibers for the preparation of the proposed concrete, according to the indicated specifications.
- Table 2 is also included, which indicates adjustments in dosages and PVA fibers
- REPLACEMENT SHEET (Rule 26) cement, which prevents water from being trapped between the cement starches that are initially formed.
- the rest of the water and the superplasticizer additive can be added together with the nanosilica, which is liquid.
- the whole set is mixed for 2 minutes.
- the addition of water and superplasticizer in two stages provides more workability to the mixture, since those are free to act in the lubrication of the paste since at that time the cement flocs do not appear.
- the fibers are added to the mixer, which are mixed together with the whole for another minute.
- the runoff test has been carried out, according to the specifications of the UNE 83361: 2007 standard (AENOR 2007). This test responds to the need to verify if the concrete produced is really self-compacting. In addition, it allows to verify the homogeneity of the material through the existence of exudation and / or segregation of the mixture.
- specimens have been made for the compression strength test of cylindrical specimens at the age of 24 hours, 7 and 28 days, according to the UNE 12390-3: 2003 standard (AENOR 2003).
- Test specimens have also been prepared for the Barcelona tensile strength test at 7 days, according to PrUNE 83515: 2007 (AENOR 2007).
- Table 4 shows the number of molded specimens for each concrete, while Figure 4 shows the molding of the specimens.
- the tests carried out in the hardened state are intended to characterize the mechanical properties of the concrete in order to verify whether they are compatible with the required structural specifications of the material.
- Table 3 details the number of specimens produced per concrete test.
- the release agent has been applied by hand with a damp sponge or cloth. This has resulted in the formation of spots in the form of 'water' on the exposed face of the concrete
- the release agent has been applied with a spray gun to achieve greater homogenization in the application.
