Concrete is the second most consumed material in the world after water and it is used most
widely in the construction industry due to its high compressive strength and durability. It is obtained
by mixing cement, aggregates, water and sometimes a
A) Water curing: Water curing can be done by four methods. They are:
iii) Spraying and fogging
iv) Wet covering
The precast concrete items are normally immersed in curing tanks for a
CURING OF CONCRETE.
Curing is the name given to the procedures used for promoting the hydration of the cement, and
consists of a control of temperature and of moisture movement from and into the concrete.
Curing allows continuous hydration of cement and c
SELF CURING OF CONCRETE.
1.2 Methods of Self Curing:
Currently, there are two major methods available for internal curing of concrete. The
first method uses saturated porous lightweight aggregate (LWA) in order to supply an internal
source of water, which
3. SCOPE AND OBJECTIVE
From detailed literature review in chapter-2 the following points are evident:
i) The use of self-curing compounds is necessitated in concrete to achieve maximum
hydration compared to other curing conditions.
ii) The use
4. MODELING AND ANALYSIS
The experimental programme was explained below:
i) To study the compressive strength, water retentivity, durability for M70 mix were
considered. Total 90 cubes were casted which involves different dosages ( 0%, 0.1%,
RESULTS AND DISCUSSIONS
As per experimental programme results for different experiments were obtained. They are shown in table format or graph, which
is to be presented in this chapter.
5.1 Studies on Concrete
5.1.1 Slump Test
The slump test is
After the analysis of the result of the experimental programme the following conclusions were
1. High grade concrete containing Ordinary Portland Cement with Polyethylene Glycol in
indoor curing with 0% dosage (by weight of
1. Clay masonry is widely used in construction of civil engineering structures, as clay
masonry is good at thermal and sound insulation.
2. Fire resistance is the main weakness of clay brick masonry when improper design
methods are used. Ther
