GUIDELINES TO FOLLOW WHILE STORING BLOCKS ON SITE

While storing these concrete blocks at site, following guidelines should be followed.

🚫  Do not dump concrete blocks at site.

📛Store the blocks close to the site of work so that least effort is required for their transportation.

⛔️ Unload one block at a time and stack it in regular tiers to minimize breakage and defacement.

⛔️ The height of the stack should not be more than 1.2 m. the length of the stack should not be more than 3 m. and width of the stack should not be more than 2 to 3 blocks.

⛔️  If blocks are cured for less than 28 days, then stack these blocks separately.

10 of the Largest Construction Projects in the World
#10. Great Man-Made River Project, Libya
Libya has been working on the "Great Man-Made River" (GMR) project since 1985. It is the largest irrigation project in the world. When completed, it will irrigate more than 350,000 acres of arable land and will substantially increase available drinking water in most of Libya's urban centers. The water source for the project is the underground Nubian Sandstone Aquifer System. The project is scheduled for completion in 2030.

Sieve Analysis
1- Why sieve analysis is important?

Ans: Sieve analysis is one of the most significant test for aggregates as it's used widely in road construction, the sieve analysis can determine the particle size distribution of the sample and determine the particle size range, the result of sieve analysis is used to select the suitable grade of granular material for subbase. Also the sieve analysis is used to determine the aggregate mix proportion of asphalt mixture.

2- How do you know the tested material for subbase layer is ok? how do you know in which size we have a shortage? or in which size we have over or under size?

Ans:  sieve analysis should be carried out for granular material in order to determine the percent of passing for each size fraction relevant to the standard table, the result compared with the standard table in order to determine the grade of material from A to D. The shortage of each size can be clearly specified by comparing the  percent passing with the range of standard table, if the percent passing is more than the range of the standard table this is mean the material have a shortage in that size. The oversized mean the diameter of the  material is larger than the standard size, and undersize is mean the material diameter is smaller than the standard size mentioned in the standard table, if the percent of passing of material at specified sieve size larger than the percent of passing of standard table, the phenomena is the oversize and vice versa for the undersize.

Recent Building Technologies
👉 Business Intelligence( BI)
The construction industry collects lots of data. But do contractors analyze that data to make intelligent decisions about their projects and overall business strategy? Business Intelligence in construction is is the gathering of data largely produced through construction management and project management software and sorting and analyzing it to make intelligent business decisions. Identifying areas where increased project efficiencies and productivity can be achieved; the ability to more accurately bid and scale for future projects; spotting consistent problems on projects and developing strategies to solve them are some of the many benefits of BI.

3- is it possible to shake you sieve set for only 10 minutes?

Ans: Yes, it's possible. The shaking time for most aggregate sample is 10 minutes, the shaking time should be checked after the test, if the shaking time prior the test is not enough, the test should be repeated.

Dams- from Ancient to today
👉 Jawa Dam

The first known dam to be built is the Jawa Dam. Located in modern-day Jordan, the Jawa Dam was originally constructed around 3,000 BC in what was then Mesopotamia. While most ancient dams were simple gravity dams constructed of gravel and masonry, the Jawa Dam was reinforced with rock fill behind the upstream wall in order to protect the wall from water pressure breach. This safety feature was incredibly innovative for this time period. In its prime, the Jawa Dam was 15 feet tall, 80 feet long, with a base of 15 feet. It created the Jawa Reservoir that had a capacity of 1.1 million cubic feet. The Jawa Dam site is arguably the most important archaeological site in the history of large-scale water projects, and the dam itself was so well designed and constructed that the ancient structure stood until just a few years ago, when it was partially ruined due to physical intervention.

4- How do you choose your sieve trails for the whole test sample? why we can not sieve the whole sample?

Ans: The trail size should be based on the suitable size which prevent the overloading phenomena, the large amount of sample size can not be tested in one operation because overload may occur on some specific sieves especially smaller sieves.

5- What does overloading mean? what is the maximum permissible rate according to ASTM standards? is it depend on mesh area?

Ans: Overloading mean the sieve contain more than the permitted amount of retained material which cause the sampler particle does not get any chance to have a contact with the sieve mesh. The standard permitted retained mass on each sieve according to ASTM should not more than 7 kg per m.sq of sieve mesh.

6- Why you can not randomly prepare the test sample? do you know better methods to prepare you test size?

Ans: the aggregate samples for. Laboratory specimens should be prepared by mechanical splitters or other methods for reducing field samples to testing size in order to avoid segregation.

7- What does mean the segregation? when you have a segregated sample? how do you avoid them?

Ans: Segregation means the larger and smaller particle of aggregate separate from each other for particular mixing and testing tasks. The segregation occurred for the specific amount of sample separated from the larger amount of sample by hand or other means. To avoid segregation the specific amount of sample for testing amount should be produced by mechanical splitters

8- How do you know your table of calculation for sieve analysis is correct without double checking?

Ans: if the percent of passing of pan is 0, this means the entire calculation is correct without the need for double checking.

Formwork
Formwork, sometimes known as shuttering or casing, is the temporary or permanent molds into which concrete or similar materials are poured. It is often confused with the term 'falsework' which is the complete structure erected to support the shuttering molds.
some of the common types of formwork are:
👉Traditional timber formwork
👉Engineered Formwork System
👉Re-usable plastic formwork
👉Permanent Insulated Formwork
👉Stay-In-Place structural formwork systems.
👉Flexible formwork

Have you ever seen giant holes in water?

If you did, these giant holes are nothing but one type of spillway known as bell-mouth spillway. A spillway is a structure used to provide controlled release of flows from a dam or levee into a downstream area to help prevent floods from damaging or destroying a dam. Some spillways are designed like an inverted bell so that water can enter all around the perimeter. These uncontrolled spillway devices are also called: morning glory, plughole, glory hole, or bell-mouth spillways. In areas where the surface of the reservoir may freeze, bell-mouth spillways are normally fitted with ice-breaking arrangements to prevent the spillway from becoming ice-bound.
