TL;DR: In this paper, the size effects of SiO2 nano-particles on compressive, flexural and tensile strength of binary blended concrete were investigated, and it was concluded that concrete specimens containing SiO 2 particles with average diameter of 15-nm were harder than those containing 80-nm of siO2 particles at the initial days of curing.

TL;DR: In this article, the effects of SiO2 nanoparticles on both mechanical properties (compressive, split tensile and flexural strength) and physical properties (water permeability, workability and setting time) of binary blended concrete have been investigated.

TL;DR: In this paper, the effects of nano silica on short-term drying shrinkage of mortars with palm oil fuel ash (POFA) during the first 28 days of curing were investigated.

TL;DR: In this article, an experimental study was done, designed to examine the water permeability and setting time of Portland cement mortar with nano-SiO2 admixed at 0.5, 1, 1.5 and 2 wt% of cement.

TL;DR: In this paper, the authors examined both the interaction between adjacent buildings due to pounding and interaction between the buildings through the soil as they affect the buildings' seismic responses, and the results indicated that pounding worsens the buildings’ condition because their seismic responses are amplified after pounding.
