Can Infrared thermography be used to inspect cracks in a building?
What is the reason behind keeping the cement surface uneven before placing tiles?
So that, when you are tapping it, will level bed to set and air pocket will get out giving a level bed for bonding.

The physical tests to be conducted for fly ash at the site
The intensity of these processes depends largely on
the ash fineness (particle size and particle size
distribution) so that the pozzolanic reactivity increases
with the specific surface of the ash. International standard
ASTM C 311 describes the procedures of chemical and
physical methods for characterization of fly ash, and
standard ASTM C 618 provides chemical and physical
criteria related to classification.
all samples of ash that were for seven days exposed in a
humid environment contains a substantial amount of
amorphous glassy-matter, but also crystal phase of
feldspar, melilite, mullite, very little anhydrite and
quartz is present. In the specimens that were
subjected for 28 days besides the already mentioned
minerals a trace of calcite occurs in the sample;

Thousands of engineering graduates from Indian universities are not employable as the education they receive is short of employable skills. What are the best skill-based courses for a graduate engineer to be employable?
There is not a simple answer to your question. It depends on what type of engineering you are studying. The best advice is to read some job advertisements for graduate engineering jobs. Note down what skills are requested. Some of these will be addressed by your engineering program. Other skills youRead more
There is not a simple answer to your question. It depends on what type of engineering you are studying. The best advice is to read some job advertisements for graduate engineering jobs. Note down what skills are requested. Some of these will be addressed by your engineering program. Other skills you can build on the side. These include communication and collaboration skills.
Engineers spend 60% of their time communicating and <20% of their time doing technical stuff. Your engineering program will do a very good job of developing your technical skills but it’s the social skills of collaboration that will determine your ultimate success in the workplace. So, work hard at all those group projects. Figure out what it takes to get everyone engaged. One day, this will be a vital skill in your workplace.
See lesswhat is the importance of expansion joints on concrete bridge decks?
The importance of expansion joints on concrete bridge deck is that they are designed to allow for continuous traffic between structures while accommodating movement, shrinkage and temperature variations on reinforced and prestressed concrete, composite and steel structures.

The various causes of providing cavity wall are as follows :-
1. Damp Prevention :- Cavity walls reduces the chance of moisture intrusion from outer leaf to the inner leaf and thus helps in keeping inside of the building free from dampness.
2. Thermal Insulation :- The air in the cavity wall acts as a non-conductor of heat and hence minimizes the transmission of heat from the outer leaf to the internal face of the interior leaf. Thus, cavity walls help in maintaining the thermal insulation of a premise.
3. Sound Insulation :- The air in the cavity acts as a cushion for absorbing sound. By building cavity walls, a premise may work as a sound proof zone as a large quantity of external noise gets absorbed within the cavity.
4. Efflorescence Prevention :- As dampness is not allowed to penetrate the cavity, the inner leaf of the cavity, which is always a load bearing wall, is kept free from efflorescence effects.
5. Economy :- According to ‘W. B. McKay’ (Author of Building Construction), building a 275 mm cavity wall costs less than constructing a 328 mm solid wall (which is of the minimum thickness if dampness has to be mostly avoided). This measuring data may vary from one place to another and on the specific climate of the construction site. One has to calculate the customized details before deciding the measurement of a cavity wall.

- Formation of cracks due to anomalies in the coating material or associated with the substrate elements.
- The diagnosis needs to establish the causes of cracks and identify the existing topography as well as the degree of damage.
- The study indicates a strong dependence on the variations of surface temperature and sun incidence with no agreement about the criteria regarding the best time to make the thermographic inspection in day or night
- The use of thermography to study cracks, detachment, and humidity are still being performed on an experimental basis.
- Thermography is used to observe the location of cracks
- Nowadays, the weather conditions in the country where the studies are being performed are an important variable in the process and results since they involve differentiation of heat flux for each study.
