Foundation, Concrete and Earthquake Engineering

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 ,...

Dear reader we are discussing about ASTM specification for fine aggregate for concrete. In case of concrete mix design , the designer ass...

Dear reader we have discussed about straight forward limits for fineness of sand used in concrete according to different standards of th...

Dear reader we have discussed many aspects of cracks in concrete . Plastic shrinkage cracks micro cracks, cracks due to alkali silica reac...

Fineness of fine aggregate is related to term fineness modulus ; most commonly sand. Fineness modulus is a measure to define fineness of a...

Aggregates generally contain pores; these may be of various size and extent. Some aggregates have pores within solid where other have ope...

Dear reader in this post we will discuss about identification of loess soil from other soils. We have discussed about index properties of...

We have discussed about different concreting method for pile foundation . Now we will discuss about specification for concrete mixing and ...
