Foundation, Concrete and Earthquake Engineering

Dear reader throughout our last few posts we were discussing about field identification of different types of soils. In this regard, it ha...

In our previous posts we have learnt about shaking test and strength test for differentiating silt from clay . Now we will discuss about ...

Concrete member , after properly placing, have to undergo curing. This term means providing a barrier against loosing moisture from concre...

Dear reader we have learnt about diffusion through concrete . We are primarily interested on oxygen and carbon dioxide diffusion. We have ...

We have learnt in last post about difference between different processes of fluid ingression into concrete. Diffusion is a process in whi...

For evaluation of earthquake hazard, every probable sources of earthquake activity, for a desired region or site, have to be identified an...

Dear reader fluids travels through concrete not only by permeability but there have also other mechanisms. Here we will discuss about the...

It is now clear to us that if we do not expect any moisture to move from or to aggregate , the pores in it must be filled with water. But ...

In case of concrete mix design , after all considerations for strength and durability, a water-cement ratio is fixed which is followed by ...

Dear reader we have learnt some aspects of porosity aggregate of concrete in last posts. Where we come to learn that water absorption is ...

We have already learnt that aggregate have pores which can absorb water form environment and also from fresh concrete . The absorption dep...

We know that concrete aggregates inherently have pores and their sizes can vary over a wider range. Of these, the largest may be only vis...

Dear reader we have some idea about soundness in our previous posts. Now we can differentiate volume changes depending on physical and che...

Subsurface investigation is essential for design with reliable safety. As discussed in last post, residual soils are competent but there ...

We have discussed many posts about residual soil ; here we will discuss about some residual soil. Our concern here is laterites and saprol...

It should keep in mind that water/ moisture is the main enemy to soil and geotechnical engineering. While try to simulate a soil sample t...

Dear reader we have discussed about water table fluctuation and its detrimental effects on foundation performance. Here we like to discu...

We know soil is of two types depending on origin, namely residual soil and transported soil ; we have discussed many posts about both typ...

Pumping of concrete is very common in today’s concreting in relatively less accessible construction site and also concreting in greater e...

Dear reader we will discuss here about organic content in fine aggregate. We will not include consequence of organic content in concrete ,...
