Concrete with superabsorbent polymer - ScienceDirect

2018-1-1  Abstract. Superabsorbent polymers (SAPs) are cross-linked polymers with several unique characteristics that can be exploited for a number of applications in concrete technology. Indeed, recent years have seen a growing interest in the use of SAP to improve the performance and long-term durability of concrete structures.

Polymer concrete - ScienceDirect

2019-1-1  Polymer concrete (PC) is a type of concrete where aggregate and polymers are mixed together to make a composite with higher strength, significant water tightness, and higher durability resistance when compared with conventional Portland cement concrete.

Chloride migration in concrete with superabsorbent polymers

2015-1-1  Superabsorbent polymers (SAP) can be used as a means for internal curing of concrete. In the present study, the development of transport properties of concrete with SAP is investigated. The chloride migration coefficient according to NT BUILD 492 is used as a measure of this. Twenty concrete mixtures are tested 7, 14, and 28 days after casting.

Study on the post-fire properties of concrete with ...

Table 2 shows the proportions of constituents in the mixes studied and the results in the fresh state. The absolute volume method was used to design the concrete mixes keeping the water-cement ratio constant at 0.46 with 370 kg/m 3 cement and 170 l/m 3 water. Superplasticizer was added during mixing of concrete to achieve consistency class S4 (160–210 mm).

2021-8-15  The concrete blocks were produced with the addition of polymeric recycling waste and luminescent materials, exposed to solar radiation, and tested for mechanical strength. The results of the experiments showed that the polymer residue in concrete significantly increases photon emission, especially when it is processed by extrusion.

Arching in concrete slabs strengthened ... - ScienceDirect

2019-4-1  The theory for the prediction of ultimate capacity was based on the deformation theory of McDowell et al. and the effects of arching and bending were considered separately, although in reality compression in concrete was due to the action of both arching and bending. This arching analysis was further developed , for bridge deck slabs with high strength concrete (>70 N/mm 2).

This paper presents the results of an experimental study conducted to evaluate the effect of recycled tyre polymer fibres (RTPF) on the mechanical and durability properties of concrete after high temperature exposure. RTPF were used as an alternative to the commonly used polypropylene fibres (PPF) in concrete. Therefore, five different concrete mixes were tested: plain concrete, four mixes ...
