As the building industry takes up a significant part in the energy utilization of a country, builders and engineers are searching for better approaches to limit the energy utilization in buildings in order to prevent environmental pollution [1,2]. The operational energy (OE) of buildings alone corresponds to 30-40% of the complete power consumption globally [3]. The building sector may be looked at while the motorist that is prominent of use and greenhouse gasoline emissions if embodied requirements. Hence, EE and OE linked to building materials and transport requirements linked to the transportation to build people tend to be taken into consideration [4].

“…The pozzolanic activity of the RHA was evaluated rapidly as demonstrated by Nair et al [40]. Many researchers demonstrated the applicability of the RHA as a cement replacement to enhance the strength characteristics of the cement concrete and mortar [42][43][44][45][46][47][48]. The density of concrete raised with more fineness of RHA, while the voids decrease, up to the optimum cement replacement [49].…”

“…The density of concrete raised with more fineness of RHA, while the voids decrease, up to the optimum cement replacement [49]. The microstructural characteristics of RHA blended with cement in the concrete present us with beneficial modification of concrete characteristics [38,44,[50][51][52][53][54][55][56]. The mechanism behind the successive reactions in cement blended with RHA particles was presented by Le and Ludwig [57].…”

Ceramic waste powder (CWP) and rice husk ash (RHA) are one of the highly produced waste materials from tiles industry and rice processing units respectively. Using these materials in concrete as a part replacement for cement offers several advantages like reducing the burden on landfills, reducing the construction cost by replacing costly cement and improvement in performance of concrete etc. due to their mineral composition. In the current study, an effort was made to partly replace the cement with CWP and RHA. Concrete design mix was carried out by using 0, 5, 10, 15 and 20% CWP and varied proportions of RHA were tried on the optimum CWP for cement replacement (0, 5, 10, 15, 20%). Tests were carried out on the fresh and hardened concrete specimens to study the mechanical properties of concrete. Analysis of the test results indicate that 15% CWP yielded best results and 10-15% RHA in combine proportion was found to be the optimum replacement of cement offering higher strength when assessed to the conventional concrete. Maximum compressive strength achieved at 15% CWP and 15% RHA whereas, the flexural strength and split tensile strength were attained at 15% CWP and 10% RHA dosage.

“…In actual engineering, the surface of a concrete structure is covered with a layer of plastering mortar to protect the concrete from erosion and provide a decorative effect [15,16]. Under fire, the plastering layer can act as a barrier to decelerate the change of temperate of the internal concrete structure.…”

At present, the research on the high temperature degradation of concrete usually focuses on only the degradation of concrete itself without considering the effect of the plastering layer. It is necessary to take into account the influence of the plastering layer on the high temperature degradation of concrete. With an increase in the water/cement ratio, the explosion of concrete disappeared. Although increasing the water/cement ratio can alleviate the cracking of concrete due to lower pressure, it leads to a decrease in the mechanical properties of concrete after heating. It is proved that besides the water/cement ratio, the apparent phenomena and mechanical properties of concrete at high temperature can be affected by the plastering layer. The plastering layer can relieve the high temperature cracking of concrete, and even inhibit the high temperature explosion of concrete with 0.30 water/cement ratio. By means of an XRD test, scanning electron microscope test and thermogravimetric analysis, it is found that the plastering layer can promote the rehydration of unhydrated cement particles of 0.30 water/cement ratio concrete at high temperature and then promote the mechanical properties of concrete at 400 °C. However, the plastering layer accelerated the thermal decomposition of C-S-H gel of concrete with a water/cement ratio of 0.40 at high temperature, and finally accelerate the decline of mechanical property of concrete. To conclude, the low water/cement ratio and plastering layer can delay the deterioration of concrete at high temperature.
