3. Loading. Without shock apply and increase the load

continuously at a constant rate within the range of 0.2
N/(mm2 ·s) to 0.4 N/(mm2 ·s) until no greater load can be
sustained. On manually controlled machines as failure is
approached the load-indicator pointer will begin to slow

down; at this stage operate the controls rapidly and
smoothly to maintain as far as possible the specified loading
rate. Record the maximum load. Normal failures are
reasonably symmetrical. Note any unusual failures and the

appearance of the concrete

A) Calculation estimated in-situ cube strength

= D X measured of compressive
1.5 + 1/λ strength of core

D = 2.5 for cores drilled horizontally (for precast units
perpendicular to height when cast); or 2.3 for cores drilled
vertically (for precast units parallel to height when cast);

λ = the length (after end preparation)/diameter ratio

DISCUSSION : * Interpret and comment the results obtained

a. Find the result of coring test
b. It is suitable or not depends on your result. Explain the
result

CONCLUSION
a. Give your conclusion from this experimental and explain the
result you get.

REFERENCES: Give at least 5 references you refer
